COMMONWEALTH vs. PEDRO POLANCO JIMENEZ.

CORDY, J. The defendant was convicted of trafficking in cocaine and heroin in amounts exceeding 200 grams, and of possessing controlled substances with intent to distribute in a school zone. G. L. c. 94C, §§ 32E (b) (4), (c) (4), and 32J.

Prior to trial, he moved to suppress drugs and drug paraphernalia seized from an apartment pursuant to a search warrant containing a provision permitting the police to enter and search the apartment without first knocking, announcing their presence, and stating their purpose (the "no-knock provision"). The motion was denied and the evidence introduced at his subsequent trial. On appeal, the Appeals Court reversed the motion judge's denial of the motion to suppress, holding that the affidavit on which the warrant issued was inadequate to support the no-knock provision, and that even if the no-knock provision had been properly included in the warrant, it became ineffective when the search was executed because the exigencies claimed in the affidavit no longer existed. Commonwealth v. Jimenez, 53 Mass. App. Ct. 902 (2001). We granted the Commonwealth's application for further appellate review. Because we conclude that the circumstances justifying the inclusion of the no-knock provisions were not present at the time of the search, the motion should have been allowed, and the items seized suppressed.

1. Facts. We glean the following facts from the affidavit submitted in support of the warrant application and from the undisputed testimony adduced at the hearing on the motion to suppress.

On November 24, 1997, a search warrant with a no-knock provision was issued on the application of Sergeant Thomas Gaffney of the Worcester police department for an apartment occupying the third floor of a residence at 5 Eastern Avenue in Worcester, and for any persons who might be found on that premises. The property sought included heroin, drug distribution paraphernalia, financial records, money, and documents pertaining to the occupancy of the apartment. The application for the search warrant was the product of several months of police work including the collection of informant information, the execution of a controlled buy, and extensive use of police surveillance. The investigation focused on two individuals nicknamed Papo (later identified as codefendant Jose Carro), and Hector (later identified as the defendant), and a white Chevrolet Lumina automobile that they apparently used to make drug deliveries.

As set forth in the affidavit of Sergeant Gaffney, Papo and

Page 215

Hector operated their drug-selling business in a secretive manner. In order to purchase drugs from them, one needed to "beep" a specific telephone number. By a return telephone call, the order would be taken and directions given to a location where the drugs would be delivered. The location at which the drugs were stored and processed for distribution was never made known to the buyers, and was only discovered through police surveillance of the white Lumina after it was used to make deliveries. During the three-month period of police surveillance, Papo and Hector moved their operation from another location to the apartment at 5 Eastern Avenue.

After obtaining the search warrant, the police conducted two days of additional surveillance at 5 Eastern Avenue. At 6:23 P.M. on November 26, 1997, after observing both suspects enter the apartment, the police proceeded to execute the warrant. At the time of execution, it was dark; the suspects were not seen at the windows in the apartment; there were no apparent lookouts; the front door to the building that led to a common hallway and staircase and that normally required a key to open, gave way to "a little push"; and the officers proceeded up the stairs, breaking down the door to the apartment with a battering ram as they announced their presence. [Note 1] Papo and the defendant were present in the apartment and were arrested.

The search proved productive. Heroin and cocaine were seized, as was equipment for their processing, packaging, and distribution. Also seized were pagers, $3,099 in cash, a handgun, and thirty-seven rounds of ammunition.

2. Discussion. The requirement that police "knock and announce" their presence and purpose prior to the execution of a search warrant has long been a part of our common law. Commonwealth v. Macias, 429 Mass. 698, 700 (1999). See Commonwealth v. Antwine, 417 Mass. 637, 638 (1994) (holding that, as general rule, police "must knock, announce their identity, and state their purpose"); Commonwealth v. Scalise, 387 Mass. 413, 418 n.5 (1982) (applying rule to search warrant

Page 216

as well as arrest warrant); Commonwealth v. Cundriff, 382 Mass. 137, 140-147 (1980), cert. denied, 451 U.S. 973 (1981) (tracing roots of common-law knock and announce rule to Seventeenth Century England). It has also been incorporated into the protections afforded by the Fourth Amendment to the United States Constitution against unreasonable searches. Wilson v. Arkansas, 514 U.S. 927, 934 (1995) (common-law knock and announce principle is "element of the reasonableness inquiry under the Fourth Amendment"). "Among the purposes of this rule are the protection of individual privacy interests and the desire to minimize the potential for violence or property damage." Commonwealth v. Macias, supra at 701. See Richards v. Wisconsin, 520 U.S. 385, 393 n.5 (1997); Commonwealth v. Cundriff, supra at 140-141.

It is equally well established that the failure of the police to knock and announce their presence may be justified in circumstances where concern for the safety of the officers executing the warrant or fear that a substantial portion of the evidence sought might be destroyed or secreted is present. [Note 2] See Commonwealth v. Macias, supra at 701; Commonwealth v. Antwine, supra at 639; Commonwealth v. Scalise, supra at 418; Commonwealth v. Cundriff, supra at 147 n.15. See also Wilson v. Arkansas, supra at 936. In order to justify suspension of the knock and announce requirement, the Commonwealth must establish that there is probable cause to believe that, in the particular circumstances of the search to be undertaken, evidence will be destroyed or officer safety put at risk if the rule is observed. Commonwealth v. Macias, supra at 701, 703. [Note 3] This showing must ordinarily be made in advance of the search

Page 217

by affidavit submitted to the magistrate at the time of the warrant application. Commonwealth v. Scalise, supra at 420. See Commonwealth v. Benlien, 27 Mass. App. Ct. 834, 835 (1989). Such a showing can also be made after the fact, even if the warrant did not authorize a no-knock entry, if exigent circumstances arise at the threshold of the search justifying both the unannounced entry and the failure to obtain prior judicial authorization. Commonwealth v. Scalise, supra at 422 n.8. Even a no-knock entry properly authorized in advance of a search may turn out to be unlawful if the situation actually encountered by the police at the time of the warrant's execution is less exigent than what was anticipated. Consequently, the police who execute a search warrant that dispenses with the knock and announce requirement must make a "threshold reappraisal" of the actual circumstances they face before they may disregard the requirement. Id. at 421. Commonwealth v. Macias, supra at 704. Commonwealth v. Benlien, supra at 837. Cf. Richards v. Wisconsin, supra at 395 ("reasonableness of the officers' decision [to enter without knocking and announcing] must be evaluated as of the time they entered the [premises]").

In the present case, the Commonwealth attempted to demonstrate that the safety of the executing officers would be jeopardized and evidence might be destroyed if the officers were required to knock and announce their presence and purpose. To this end, the affidavit submitted in support of the warrant application included information that the suspects kept secret the location of the apartment where they stored their drugs, and moved it at least once during the period of police surveillance; that the apartment was located on the third floor of a residential building whose street-level door was kept locked; that it was not possible to approach the building without being seen; that heroin and cocaine could easily be disposed of by flushing them down the toilet; and that it was "common" for

Page 218

drug dealers to have firearms and for firearms to be confiscated in the execution of search warrants of this type.

In authorizing the no-knock execution of the warrant, the magistrate did not indicate whether it was justified on the basis of officer safety, likely destruction of evidence, or both. In denying the motion to suppress, the judge identified as "unique facts" supporting the request for the no-knock provision that there would be two suspects in the apartment; that it would be difficult to enter the building; that the officers' presence would become known before they reached the third-floor apartment; and that the drugs were stored in the apartment in secret. On the basis of these findings, he concluded that the affidavit adequately demonstrated both safety concerns and concerns that contraband would be destroyed. The judge made no findings regarding whether the circumstances as they existed at the time of the search continued to justify dispensing with the knock and announce requirement, even though that issue had been specifically raised by the defendant, and much of the hearing on the motion to suppress was devoted to taking testimony on that point.

We accept the judge's subsidiary findings absent clear error but conduct an independent review of his ultimate findings and conclusions of law. Commonwealth v. Thomas, 429 Mass. 403, 405 (1999). We also acknowledge that affidavits in support of search warrants are to be approached with a view toward common sense, read in their entirety and with considerable latitude allowed for the drawing of inferences. Commonwealth v. Smith, 370 Mass. 335, 342-343, cert. denied, 429 U.S. 944 (1976), quoting Commonwealth v. Perada, 359 Mass. 147, 149 (1971). Here, the judge's acceptance of the affidavit's contents as establishing probable cause based on facts uniquely present in the particular circumstances can be sustained as to the likely destruction of evidence, but not as to the presence of safety concerns. More importantly, the uncontested evidence as to the conditions existing at the time of the search require that his ultimate ruling denying the motion be reversed.

First, with respect to concerns for safety, the affidavit described only general concerns present in the execution of any warrant authorizing a search for drugs. While it may be true, as

Page 219

the affiant asserts, "[t]hat it is common today for drug dealers to be in possession of firearms," and that firearms are "commonly confiscated" in the execution of searches for drugs, these categorical assertions do not justify dispensing with a review of the specific circumstances present in each case. [Note 4] To conclude that such general averments are adequate would amount to the adoption of a per se rule that safety concerns sufficient to warrant suspension of the knock and announce requirement are demonstrated merely by the fact that the search is for drugs. Such a rule was rejected by the Supreme Court in Richards v. Wisconsin, 520 U.S. 385, 390 (1997), as being inadequate to satisfy even the lower standard of reasonable suspicion that the dissent urges us to adopt and that is the minimum required by the Fourth Amendment. Id. at 390.

In Richards v. Wisconsin, supra, the Supreme Court reviewed a ruling of the Supreme Court of Wisconsin that the reasonableness requirement of the Fourth Amendment to the United States Constitution was satisfied by a per se exception to the knock and announce rule in the execution of search warrants in felony drug investigations. In reaching its ruling, the Wisconsin court found it reasonable to assume, based on studies, articles, and judicial opinions, that felony drug searches involve "an extremely high risk of serious if not deadly injury to the police." Id. at 390. Accordingly, it concluded that the police do not need to demonstrate specific information about dangerousness in order to dispense with the knock and announce requirement in such searches. Id. In rejecting this holding, the Supreme Court held that even though "felony drug investigations may frequently present circumstances warranting a no-knock entry,"

Page 220

it is "the facts and circumstances of the particular entry [which must justify] dispensing with the knock-and-announce requirement." Id. at 394.

While the affidavit here contained a great deal of detail about the defendant's drug operation, it contained no particular facts and circumstances suggesting that there might be weapons on the premises, that the defendant or the codefendant might carry or possess weapons, or that either had a history of weapons possession or violence. Without more, the affidavit was inadequate to establish probable cause (or even reasonable suspicion) that the officers' safety would be jeopardized by requiring them to knock and announce their presence before executing the warrant. Commonwealth v. Hernandez, 49 Mass. App. Ct. 911, 913 (2000). [Note 5]

The circumstances presented in the affidavit with regard to the likelihood of destruction of evidence lead us to a different conclusion. While the fact that drugs can often readily be disposed of in a sink or toilet is not an adequate basis on which probable cause can be found, Commonwealth v. Scalise, 387 Mass. 413, 421 (1982), it is, of course, an obvious and important factor that the magistrate may consider along with other reasons for tipping the balance and justifying an exception to the knock and announce rule. Foremost among such other reasons is the likelihood that the occupants of the dwelling will have advance knowledge of the officers' presence and purpose. Here, the information set forth in the affidavit specifically raises this likelihood in its description of the premises as having

Page 221

(1) windows overlooking the approach that the police would need to traverse in order to gain entry to the building, and (2) a locked door located several floors below the apartment to be searched. These facts, when combined with the secretive manner of the drug operation and the movement of its locus during the period of police surveillance, would adequately support inferences drawn by the magistrate that the suspects would likely notice a police presence before the police ever got to the point where the knock and announce requirement would apply, [Note 6] and that they would be prepared to dispose of the drug evidence within the premises as soon as they learned of that presence. Considering these inferences together, we conclude that the magistrate's approval of the no-knock provision was supported by probable cause to believe that the extra time afforded the occupants of the apartment by requiring the police to knock and announce their presence "would allow a significant additional portion of the evidence sought to be destroyed." Commonwealth v. Macias, 429 Mass. 698, 703 (1999). See Commonwealth v. Scalise, supra at 419, 421 & n.7 (furtive conduct and suspect's likely awareness of police surveillance adequate basis for no knock); Commonwealth v. Benlien, 27 Mass. App. Ct. 834, 836 (1989) (set up of apartment permitting lookout for police combined with physical obstacle to entry adequate basis for no knock). But see Commonwealth v. Macias, supra (apartment windows overlooking buzzer-operated front door insufficient to establish probable cause that extra time would result in substantial additional evidence being destroyed where large quantity of drugs stored in different parts of apartment and packaged in many smaller plastic packages would be difficult to dispose of quickly).

Having concluded that the warrant was properly issued, we turn to its execution. As noted, the police timed the execution of

Page 222

the warrant to coincide with the presence of both suspects in the premises, presumably to ensure the search of their persons and their arrest if contraband was found during the search. The warrant was executed after dark, there was no lookout, and the suspects were not at the windows of the apartment. Every indication was that the officers would not be and were not observed approaching the building. In addition, the locked door on the first floor merely opened when pushed and did not present any obstacle or delay to entering the building, or provide any apparent notice to the suspects three floors above. In sum, when the police arrived at the threshold of the apartment to be searched, there was no basis to believe that the occupants might have notice of their presence and might therefore be destroying evidence. The most relevant concerns set forth in the affidavit, the likelihood of being observed approaching the building and the delay likely to be encountered in breaking through the locked door on the first floor, proved not to be present at the time of execution. These are precisely the type of circumstances that require a reappraisal of the legitimacy of a no-knock entry. On these facts, such entry was no longer warranted and was therefore unlawful.

The fact that an unlawful search has occurred does not automatically result in the exclusion of any illegally seized evidence. Commonwealth v. Grimshaw, 413 Mass. 73, 78 (1992), quoting Commonwealth v. Gomes, 408 Mass. 43, 46 (1990). The Commonwealth, however, has not pointed to any reason in its brief or argument why exclusion should not be the remedy in this case. The evidence seized in the apartment should have been suppressed. Because there could not have been a valid conviction without the impermissible evidence, the judgments are vacated, the verdicts set aside, and judgments shall enter for the defendant.

So ordered.

SOSMAN, J. (dissenting). In my view, the interests of officer safety justified dispensing with the requirement that the officers knock and announce their presence when executing this

Page 223

particular search warrant. Legitimate safety concerns were adequately identified and supported in the search warrant affidavit, and reevaluation at the scene did nothing to ameliorate those safety concerns. Indeed, as the court acknowledges, ante at 220 n.5, the facts of this case fit squarely within our prior decision in Commonwealth v. Rodriguez, 415 Mass. 447, 449-451 & n.2 (1993) (Rodriguez), in which we upheld a "no-knock" entry based on the affiant's prior experience finding weapons during drug searches, notwithstanding the complete absence of any specific information about the presence of firearms at the location to be searched. Nothing in the Supreme Court's decision in Richards v. Wisconsin, 520 U.S. 385 (1997) (Richards), suggests that Rodriguez was wrongly decided or wrongly analyzed. I would therefore affirm the motion judge's denial of the defendant's motion to suppress.

1. Standard for issuance of warrant with no-knock provision. At the outset, the puzzling history of this court's adoption of a "probable cause" standard for approval of no-knock provisions must be addressed. The use of that standard is at odds with the Supreme Court's "reasonable suspicion" standard, articulated in Richards, supra at 395, at odds with virtually every other jurisdiction that has considered the issue (see note 1, infra), and is particularly inappropriate when officer safety is implicated. This court's use of a "probable cause" standard for no-knock provisions has been perpetuated without ever articulating either why it was adopted in the first place or why it is more appropriate than "reasonable suspicion." Consistent with other areas of search and seizure jurisprudence that address issues of officer safety, and consistent with other jurisdictions, our jurisprudence on no-knock provisions should adopt a standard of "reasonable suspicion."

Our most comprehensive discussion of the common-law "knock and announce" rule is found in Commonwealth v. Cundriff, 382 Mass. 137, 140-147 (1980), cert. denied, 451 U.S. 973 (1981). There, we upheld an unannounced entry to execute an arrest warrant based on "a strong possibility that an announcement by the police of their identity and purpose would have endangered themselves or others." Id. at 147. The court did not articulate a particular standard to be applied to requests

Page 224

to dispense with the knock and announce requirement, perhaps because it did not need to do so for purposes of the case as presented. The facts of the case -- arrest of a suspect following an armed robbery involving multiple guns -- would have warranted a no-knock entry on either a "probable cause" or a "reasonable suspicion" standard, and the case therefore presented no occasion to specify what standard was to be used when approving such an entry.

The reference to a "probable cause" standard for no-knock entries first surfaced in Commonwealth v. Scalise, 387 Mass. 413, 421 (1982) (Scalise). Without citation to any precedent, and without any analysis pertaining to selection of a standard for dispensing with the knock and announce requirement, the court simply announced that "[i]n order to obtain authority for an unannounced entry, the police must inform the issuing magistrate of the circumstances which give the police probable cause to believe that the evidence, i.e., the object of the search, will be destroyed." Id. The court then proceeded to opine, consistent with other jurisdictions, that the mere fact that drugs were the object of the search would not suffice for an automatic exception to the knock and announce rule. Id. However, the court concluded that the search warrant affidavit's recitation that the suspect was dealing significant quantities of marijuana and that he had moved to a different location in response to feared police surveillance was sufficient to support the inference that he was "ready to destroy the drugs" such that "the facts were sufficient to give rise to probable cause to believe that the evidence would be destroyed if the police knocked and announced their purpose before entering the apartment." Id. at 422-423. Thus, where the Commonwealth's showing had met the standard, whether formulated as "probable cause" or as "reasonable suspicion," there was no need to focus on what the standard should be. The adoption of a standard of "probable cause" occurred without any apparent consideration of whether that should in fact be the standard for a no-knock provision.

Citing Scalise, supra at 421, the court next repeated the standard as one of "probable cause" in Commonwealth v. Gomes, 408 Mass. 43, 45 (1990). In that case, the Commonwealth conceded that there was no basis for a no-knock entry, and was

Page 225

merely arguing that either the doctrine of inevitable discovery or a good faith exception should "excuse[] what occurred." Id. at 44-45. Where the search warrant affidavit in that case literally contained "no information" concerning any justification for an unannounced entry, and the record was admittedly "devoid of any showing of special need to dispense with the requirement," the court was not called on to weigh whether the affidavit met any particular standard on that subject. Id. at 46. As such, the repetition of the "probable cause" standard as part of the background jurisprudence did nothing more than repeat dictum as part of more dictum.

The next repetition, similarly devoid of analytical substance or relevance to the contested issues in the case, came in Rodriguez, supra at 450. Again, the court merely cited Scalise for the proposition that "[a] no-knock entry is permitted where the police informed the magistrate of circumstances which provided probable cause to believe that the object of the search, the contraband, would be destroyed." Id. As in Scalise, the court held that the search warrant affidavit had satisfied that "probable cause" standard, making it unnecessary to consider whether that standard was inappropriately stringent. Id. at 451.

After this "probable cause" standard was enshrined as oft-repeated dictum in the above cases, the Supreme Court issued its decision in Richards, supra. There, the Court was confronted with a State court decision that had created a blanket rule excepting all drug searches from the knock and announce requirement. As part of its explanation as to why such a categorical exception was inappropriate, the Court articulated "reasonable suspicion" as the standard to be applied to requests for no-knock entries. "In order to justify a 'no-knock' entry, the police must have a reasonable suspicion that knocking and announcing their presence, under the particular circumstances, would be dangerous or futile, or that it would inhibit the effective investigation of the crime by, for example, allowing the destruction of evidence. This standard -- as opposed to a probable-cause requirement -- strikes the appropriate balance between the legitimate law enforcement concerns at issue in the execution of search warrants and the individual privacy interests affected by no-knock entries." Id. at 394. By way of analogy,

Page 226

the Court then cited to cases articulating the "reasonable suspicion" standard for similar search and seizure problems implicating officer safety. Id., citing Maryland v. Buie, 494 U.S. 325, 337 (1990) (protective sweep of house during arrest), and Terry v. Ohio, 392 U.S. 1, 30 (1968) (pat-down search). The Court thus rejected the probable cause standard, expressly opting for the reasonable suspicion standard as one that both struck an "appropriate balance" and was consistent with related Fourth Amendment jurisprudence. The Court concluded with the observation that "[t]his showing is not high, but the police should be required to make it whenever the reasonableness of a no-knock entry is challenged." Id. at 394-395. Applying that standard to the specific facts of the case at issue, the Court held that, notwithstanding the magistrate's refusal to authorize a no-knock entry, the circumstances confronting the officers at the time of the search gave rise to a "reasonable suspicion" that the occupant of the motel room would destroy evidence. Id. at 395-396.

Two years later, on appeal from an order suppressing evidence uncovered during a search following a no-knock entry, the Commonwealth asked this court to reconsider its adherence to the probable cause standard in this area. Commonwealth v. Macias, 429 Mass. 698, 701 (1999). The Commonwealth pointed the court to the Supreme Court's decision in Richards, noted that "the common-law knock and announce rule and its counterpart under the Fourth Amendment to the United States Constitution derive from the same source, English common law, and implicate the same concerns," and argued that the same standard should therefore be utilized. Commonwealth v. Macias, supra. The Commonwealth's argument was rebuffed in a single sentence, without discussion or explanation: "We see no reason, however, to depart from the rule we have previously followed." Id. This curt rejection of a soundly reasoned argument would be understandable if "the rule we ha[d] previously followed" had itself been adopted for some articulated reason. As outlined above, however, the probable cause standard had been adopted without articulating any reason, in a case for which the precise standard was of no consequence to the outcome, and had merely been repeated in other cases where the outcome was similarly unaffected by the choice of standard.

Page 227

Normally, when this court decides that our common law, State statutes, or Constitution impose requirements different from those imposed by the Supreme Court under comparable Federal law, we take pains to explain the reasons for such differences. See, e.g., Dahill v. Police Dep't of Boston, 434 Mass. 233, 236-237, 242-243 (2001) (explaining why interpretation of "handicap" under G. L. c. 151B, § 1 [17], was contrary to Supreme Court's interpretation of "essentially identical" term in Americans with Disabilities Act); Commonwealth v. Gonsalves, 429 Mass. 658, 660-669 (1999), S.C., 432 Mass. 613 (2000) (explaining reasons for differentiating between Fourth Amendment requirements for exit order from vehicle articulated by Supreme Court and requirements under art. 14 of the Massachusetts Declaration of Rights); Commonwealth v. Upton, 394 Mass. 363, 371-377 (1985) (explaining our continued application of Aguilar-Spinelli analysis under art. 14 where Supreme Court had abandoned it for purposes of Fourth Amendment). As pointed out by the Commonwealth in Commonwealth v. Macias, supra, our common-law knock and announce requirement has the same origin as the Fourth Amendment's knock and announce requirement and serves identical purposes. Compare Commonwealth v. Cundriff, 382 Mass. 137, 140-146 (1980), with Wilson v. Arkansas, 514 U.S. 927, 931-936 (1995). To date, this court has articulated no reason for applying a standard for no-knock provisions that is higher than or different from the standard used for Federal constitutional purposes. I am persuaded that the Supreme Court's adoption of a "reasonable suspicion" standard is sound, and that standard has now been widely adopted in other jurisdictions. [Note Dissent-1] This court's adherence to a standard of "probable cause" for purposes of an

Page 228

exception to the knock and announce requirement stands as an anomaly in this country's jurisprudence on the subject. The one-sentence conclusion in Commonwealth v. Macias, supra, seeing "no reason" to depart from earlier dictum, does not strike me as an adequate basis for our utilizing a different standard.

Adherence to the probable cause standard, whatever its hidden merits might be with respect to concerns about destruction of evidence, is wholly inconsistent with our related jurisprudence concerning risks to officer safety. If reasonable suspicion as to the presence of such dangers is insufficient to dispense with the knock and announce requirement, that translates to the following unacceptable scenario: officers who have an objectively reasonable belief, based on specific and articulable facts, that knocking and announcing their presence will pose a danger to themselves (or others) will nevertheless be required to knock and announce and to endure the risk of injury (or even death) that they have objectively and reasonably predicted. Despite the

Page 229

objective reasonableness of their concerns, officers will be forced to forgo precautions that they reasonably believe are necessary for their protection unless they can literally demonstrate "probable cause" for their concerns. We have never, in any other aspect of our search and seizure jurisprudence, required officers to run such risks to their safety, and we should not do so here. [Note Dissent-2] "Certainly it would be unreasonable to require that police officers take unnecessary risks in the performance of their duties. . . . [W]e cannot blind ourselves to the need for law enforcement officers to protect themselves and other prospective victims of violence in situations where they may lack probable cause for an arrest." Terry v. Ohio, 392 U.S. 1, 23-24 (1968).

Rather, a standard of "reasonable suspicion" has uniformly been applied to search and seizure practices involving officer safety. As referenced by the Supreme Court in Richards, supra at 394, police executing an arrest warrant may conduct a sweep of the premises if they possess "a reasonable belief based on specific and articulable facts that the area to be swept harbors an individual posing a danger to those on the arrest scene." Maryland v. Buie, 494 U.S. 325, 337 (1990). See Commonwealth v. Bowden, 379 Mass. 472, 478 (1980) (police arrested suspect in hallway of apartment; sweep search of basement justified where "a security check was reasonably believed necessary by the police to ensure their personal safety"); Commonwealth v. Walker, 370 Mass. 548, 556-557, cert. denied, 429 U.S. 943 (1976). Similarly, a pat-down frisk for weapons is justified when an officer "has reason to believe that he is dealing with an armed and dangerous individual," to be judged by "whether a reasonably prudent man in the circumstances would

Page 230

be warranted in the belief that his safety or that of others was in danger." Terry v. Ohio, supra at 27. See Commonwealth v. Fraser, 410 Mass. 541, 544 (1991) (frisk justified where officer "reasonably believed that the defendant was armed and dangerous"). A search of an automobile for weapons is allowed "when, given other suspicious circumstances which justified a stop, an officer had no information whatsoever that a gun may have been in the vehicle, but still had reason to be concerned with his and others' safety." Commonwealth v. Vazquez, 426 Mass. 99, 103 (1997), citing Commonwealth v. Santana, 420 Mass. 205, 213 (1995), Commonwealth v. Moses, 408 Mass. 136, 141-142 (1990), and Commonwealth v. Almeida, 373 Mass. 266, 272 (1977). "[I]t does not take much for a police officer to establish a reasonable basis to justify an exit order or search based on safety concerns." Commonwealth v. Gonsalves, 429 Mass. 658, 664 (1999). It is unprecedented for this court to hold that an officer's reasonable belief about the presence of weapons is insufficient justification for such intrusions on otherwise protected expectations of privacy. Consistent with this long-standing precedent imposing a standard of mere "reasonable suspicion" when the issue is one of safety, we should impose the same standard when the Commonwealth seeks to show that safety concerns justify dispensing with the knock and announce requirement. [Note Dissent-3]

2. The affidavit. Applying what I believe to be the correct

Page 231

standard to the search warrant affidavit in this case, I am satisfied that that affidavit supported a reasonable belief, based on specific and articulable facts, that the occupants of the apartment would likely be armed and that knocking and announcing the presence of police would unreasonably increase the danger to the officers executing the warrant. The affidavit first supported the officer's belief that the suspects were involved in large-scale distribution of both heroin and cocaine. One of the informants reported that the suspects dealt in "large amounts" of both drugs, and made "numerous" sales. The operation was one of long standing, as the informant's reports covered a period of "several months." The operation was also of some sophistication. Neither of the informants had any information as to where the drugs were presently kept -- the dealers made no sales on site, kept the stash location secret from their customers, and moved their location after their vehicle had been stopped by police. [Note Dissent-4] Thus, the affidavit supported the reasonable belief (and even established probable cause to believe) that the suspects were substantial, experienced dealers who kept a sizeable stash of two separate drugs, along with significant cash proceeds.

On the subject of weapons, the affidavit referenced the vice squad's experience with "this type" of search: "[M]embers of the vice squad commonly confiscated firearms in the service of search warrant[s] of this type." While that sentence was introduced with an insufficient generalization about the propensity of drug dealers to carry weapons ("it is common today for drug dealers to be in possession of firearm[s]"), the sentence concluded with a reference to the actual experience of that vice squad, in that city (Worcester), with warrants of that

Page 232

type (i.e., involving significant drug operations). [Note Dissent-5] With that information, a reasonably prudent person in the position of the officers executing the warrant would have objective reason to believe that these suspected dealers would similarly be armed. [Note Dissent-6]

Indeed, despite espousing a standard of "probable cause" by which to assess the likelihood that occupants would be armed, this court previously held that an officer's prior experience finding weapons during drug searches, coupled with information that the drug dealer was dealing in significant quantities, sufficed to justify an unannounced entry to conduct a search. Commonwealth v. Rodriguez, 415 Mass. 447, 450-451 (1993). If anything, the facts set forth in the search warrant affidavit in that case were sketchier than those set forth in the present affidavit. In Rodriguez, the affidavit recited an informant's report that the suspect had eight or nine ounces of cocaine for sale. Id. at 448. The informant had no information concerning firearms, and the affidavit contained no information specifically connecting the suspect with firearms. Id. at 449-450 & n.1. However, the officer's affidavit cited his own experience "that drug dealers often carry weapons to protect themselves from rip offs by other drug dealers, and that these weapons are usually handguns." Id. at 449 n.1. The affidavit also stated that the officer had been present "many times on past raids when our officers have recovered [s]uch handguns," and that he had been present when an officer "was shot with a handgun on a drug

Page 233

raid." Id. There was no specificity as to what was meant by "often," "usually" or "many times"; no reference to any particular characteristic of the other gun-toting dealers that could be viewed as comparable to some characteristic of the dealer at issue; and no reference to any similarity between the search that had resulted in a shooting and the anticipated search. [Note Dissent-7] This court, in a unanimous opinion, concluded that the "sophistication on the part of the occupant" of the premises [Note Dissent-8] and the officer's experience with handguns during drug-related searches "provided probable cause for the magistrate to conclude that the police need not announce themselves." Id. at 451.

In apparent recognition of the fact that Rodriguez would be dispositive of the present case, the court suggests in a footnote that Rodriguez is no longer good law in the wake of the Supreme Court's decision in Richards. Ante at 220 n.5. The reasoning, apparently, is that because Richards prohibited a blanket no-knock exception that would apply to all drug searches, references in affidavits to characteristics that would be common among many drug dealers, or even references to an officer's common experience with drug dealers, must be deemed insufficient lest they create the equivalent of a blanket exception. The logic is faulty, as is the interpretation of Richards.

In Richards, the Supreme Court of Wisconsin had ruled that, without needing to present any information concerning the proposed search, a mere showing of probable cause that drug dealing was involved meant that the officers " 'necessarily have reasonable cause to believe exigent circumstances exist' to justify a no-knock entry." Richards v. Wisconsin, 520 U.S. 385, 389 (1997). The Court rejected the use of such an automatic exception to the knock and announce requirement because,

Page 234

notwithstanding the fact that most drug searches did indeed involve risks of both evidence destruction and officer safety, it was still possible that particular circumstances might eliminate those risks. Id. at 393. As examples, the Court hypothesized a search being conducted at a time when only innocent persons, not the suspected drug dealers, were present, or a situation where the officers already knew that the drugs "were of a type or in a location that made them impossible to destroy quickly." Id. [Note Dissent-9] The Court did not suggest that, absent some such countervailing considerations, an affidavit's recitation of the customary concerns surrounding drug investigations, which "frequently do[] pose special risks to officer safety and the preservation of evidence," would be insufficient for a no-knock entry. Id. Indeed, the Court recognized as "indisputable that felony drug investigations may frequently involve" both "a threat of physical violence" and "reason to believe that evidence would likely be destroyed." Id. at 391, quoting Wilson v. Arkansas, 514 U.S. 927, 936 (1995). Thus, where an affidavit recites facts that would support a reasonable suspicion as to either or both of those risks, the mere fact that those same facts are frequently encountered in drug investigations does not make them any less weighty. The point of Richards is that such facts cannot be automatically assumed for literally all drug searches, as particular circumstances may operate to eliminate the risks that would otherwise be likely in drug searches. [Note Dissent-10]

Nothing in the current affidavit, or in the affidavit at issue in

Page 235

Rodriguez, supra, suggests any reason to believe that the risks ordinarily inherent in such searches had been eliminated or even reduced. Nor does the affidavit rely on facts that would be true of "all" drug investigations. Not every drug dealer deals in "large amounts." Not every drug dealer deals in both heroin and cocaine. And not every local police department has the experience of "commonly" finding weapons during drug searches in that particular city or town. An officer can reasonably believe (as turned out to be true here) that a large-scale, sophisticated dealer in both heroin and cocaine, who keeps his sizeable stash in a city where other drug dealers have "commonly" armed themselves, is also likely to be armed. Nothing in Richards suggests that there is anything unreasonable about such a belief, and nothing in Richards undermines this court's prior decision in Rodriguez. The concerns about weapons articulated here were at least as well founded as those articulated in Rodriguez, supra, and the result should be the same.

3. Reevaluation at the scene. I will accept, at least for purposes of argument, that the absence of any lookout and the unexpected ease with which the officers gained access to the building reduced the risk that any significant amount of drugs would be destroyed during the interval following a knock and announcement of police presence. [Note Dissent-11] Those facts, however, did not diminish the risk that the occupants would be armed or

Page 236

preclude the occupants from resorting to weapons. The officers' ability to reach the threshold of the apartment unnoticed meant that the occupants would have less time in which to retrieve (and perhaps load) any weapons they had, but the time period during which the officers would have to await a response to any knock and announcement prior to forcible entry would still be ample time in which to retrieve and ready a weapon.

As noted in Rodriguez, supra at 449 n.1, drug dealers carry weapons principally to protect themselves (and their valuable stash of drugs and drug proceeds) from robbery. It is reasonable to expect, in light of that purpose, that weapons at the stash site are kept loaded and near at hand. One would therefore expect that such a drug dealer occupant, once notified of the presence of police at the door, would be able to arm himself in a matter of a few seconds. Additional advance notice, by way of lookouts or by awareness of someone breaking into the building two floors below, would not be necessary. (Indeed, when the court justified a no-knock entry on grounds of likely presence of weapons in Rodriguez, supra, it did so despite the fact that, as here, the officers' presence would not have been known prior to

Page 237

their actual arrival at the door. Id. at 451.) While the brief interval following a knock and announcement may be insufficient time to accomplish much in the way of evidence destruction (but see note 11, supra), it is quite sufficient for purposes of grabbing a gun that is, in all likelihood, loaded and close at hand.

Although this court has never addressed the issue of precisely how much time must elapse after a knock and announcement before police may proceed with a forcible entry, the time allotted must, in order to serve the purpose of the knock and announce requirement, be comparable to the time it would reasonably take an occupant to respond to the door. The purpose of the requirement is to give occupants "the opportunity to comply with the law and to avoid the destruction of property occasioned by a forcible entry." Richards, supra at 393 n.5, citing Wilson v. Arkansas, 514 U.S. 927, 930-932 (1995). See Commonwealth v. Cundriff, 382 Mass. 137, 141 (1980). While the time reasonably necessary for an occupant to respond will vary with the circumstances (including the time of day, the size and layout of the premises, and the physical condition of the occupant), and courts have therefore been reluctant to set bright-line time requirements, most cases have required a minimum wait of ten to twenty seconds, a minimum that commentators view as "unduly lenient" on the police. See 2 W.R. LaFave, Search and Seizure § 4.8(c) (1996 & Supp. 2002), and cases cited. Ten to twenty seconds would provide ample time for an occupant to retrieve (and, if need be, even to load) a weapon, plus time to hide or otherwise place himself in an opportune location from which to fire. Where, as here, the police have reasonable suspicion that an occupant may be armed, the mere fact that the police have reached the threshold unnoticed does not diminish their need to dispense with the knock and announce requirement. Rather, where weapons are concerned, every fraction of a second counts, and reasonable suspicion of the presence of weapons would still justify a no-knock entry. I therefore respectfully dissent.
