concurring:
I concur in the result reached by the majority in this case, and I write separately because of the importance of using the proper analysis to reach that result. Here, the exigency turns not simply on the possession of a Uzi by a suspected armed robber, but on the fact that the police made a reasonable effort under the circumstances to comply with the statutory requirement that they knock and announce before forcibly entering appellant’s home. With knowledge of appellant’s past aggressive use of the Uzi, the trial judge could properly find that the police could reasonably conclude that waiting longer than five seconds after announcing their presence and purpose would endanger their safety.
The Supreme Court has long recognized that the historical roots of the privacy interests in one’s home compel judicial restraint in carving out exceptions to the knock and announce requirements. Thus, in Miller v. United States, 357 U.S. 301, 313, 78 S.Ct. 1190, 1197, 2 L.Ed.2d 1332 (1958), the Court stated that “[t]he requirement of prior notice of authority and purpose before forcing entry into a home is deeply rooted in our heritage and should not be given a grudging application.” See Sabbath v. United States, 391 U.S. 585, 589, 88 S.Ct. 1755, 1758, 20 L.Ed.2d 828 (1986) (same). Following the federal courts’ interpretation of the federal statute, which is identical to the District of Columbia knock and announce statute, this court has recognized two broad exceptions to full compliance with the requirements of the statute. The first exception is based on the avoidance of mere ritual, where constructive refusal to permit entry can be reasonably inferred by the police from the action or inaction of the occupants, and the second exception arises from the exigencies of law enforcement, permitting the police to enter forcibly “without fully complying with the knock and announce statute” in order to avoid the imminent destruction of evidence or some danger to the entering *465officers. Williams v. United States, 576 A.2d 700, 703 (D.C.1990) (citations omitted).
The government’s burden to show the nature of the exigency increases, however, to the extent that the police fail to comply with the knock and announce statute. See United States v. Bonner, 277 U.S.App.D.C. 271, 275, 874 F.2d 822, 826 (1989) (citing United States v. Harris, 140 U.S.App.D.C. 270, 435 F.2d 74 (1970), cert. denied, 402 U.S. 986, 91 S.Ct. 1675, 29 L.Ed.2d 152 (1971); Masiello v. United States, 115 U.S.App.D.C. 57, 317 F.2d 121 (1963); accord, United States v. Bustamante-Gamez 488 F.2d 4, 11-12 (9th Cir.), cert. denied, 416 U.S. 970, 94 S.Ct. 1993, 40 L.Ed.2d 559 (1974)). Hence, a critical fact in the instant case is that the officers knocked and announced their identity and waited five seconds before forcing their entry into appellant’s home. Otherwise, the majority opinion could be misconstrued to stand for the proposition that whenever a semi-automatic firearm is involved, the police have exigent circumstances permitting a forced entry into a criminal suspect’s home without reference to the knock and announce requirements. See majority opinion at 463; see also id. 464 at n. 7. But that is not the law.
The decision of the United States Court of Appeals for the District of Columbia Circuit in Bonner, supra, 277 U.S.App.D.C. 271, 874 F.2d 822, is instructive.1 The court held, alternatively, that exigent circumstances justified the officers’ forced entry after eleven to twelve seconds. Id. at 275, 874 F.2d at 825. The court explained that “[t]he exigency required to justify a warrantless search differs from that required to excuse non-compliance with section 3109’s announcement provision. That degree of exigency is, in turn, greater than that needed to excuse noncompliance with only the refusal portion of section 3109.” Id. at 275 & n. 4, 874 F.2d at 825 & n. 4 (“near-complete compliance with section 3109 requires less exigency to justify entrance than does entry absent notice”). Noting that “[a] broad range of exigent circumstances has been found to justify less than full compliance with the various requirements of section 3109,” the court observed that the danger to the police “increased once the officers identified themselves and waited before the door, forced to interpret the import of the sounds within.” Id. at 275-76, 874 F.2d at 825-26.2 The court concluded, further, that the departure from the statutory requirements was “exceedingly slight,” since by knocking on two occasions and giving notice of his authority and purpose, the police officer had “thereby satisfied the principal values embodied in section 3109.” Id. at 276, 874 F.2d at 826 (citing Sabbath, supra, 391 U.S. at 589, 88 S.Ct. at 1758). Finally, the court noted that by obtaining a search warrant the officers had “eliminat[ed] that element of the exigency requirement designed to ensure that the Fourth Amendment’s Warrant Clause is not eroded by an exigency too quickly perceived by those called upon to serve on the firing line.” Id. 277 U.S.App.D.C. at 278, 874 F.2d at 828.
The trial judge in the instant case found that the police officers could reasonably conclude that they had been refused admittance. The judge reached this conclusion, however, as appellant points out, without meaningful review of whether the officers complied with the knock and announce stat*466ute. Contrary to the trial judge’s view,3 the courts must carefully scrutinize the circumstances underlying a claim of a statutory violation precisely because what is at risk is the individual’s right of privacy in his or her home as well as danger to private citizens and the police as a result of a forced entry. As was pointed out in Mar siello, supra, 115 U.S.App.D.C. at 59, 317 F.2d at 123 (after remand to trial court for findings on alleged statutory violation, where officers waited two periods of 10 to 20 seconds before forcing entry), “close cases such as this will always receive careful appellate scrutiny. It is very desirable as an aid to appellate review that the facts concerning the required preliminary steps to entry should be developed and the factors relied on by the prosecution should appear in the record and be the subject of findings.” See Griffin v. United States, 618 A.2d 114 (D.C.1992) (“where basic constitutional liberties are implicated, a more searching standard of review may be warranted”) (citing Ker v. California, 374 U.S. 23, 33-34, 83 S.Ct. 1623, 1630, 10 L.Ed.2d 726 (1963); United States v. Rodriguez, 663 F.Supp. 585, 588 (D.C.1987) (“Given the important purposes behind 3109 to protect ‘the precious interest of privacy as summed up in the ancient adage that a [person’s] house is his castle’[,] Miller v. United States, 357 U.S. at 307 [78 S.Ct. at 1194] ..., this Court concludes that 3 to 5 seconds is insufficient time to constitute ‘refused admittance’ under the statute”; 6:30 a.m.)); see also United States v. Davis, 199 U.S.App.D.C. 95, 113, 617 F.2d 677, 695 (1979) (“[t]he time that [the statute] requires officers to wait before they may construe no response as a denial of admittance depends largely on factual determinations made by the trial court”; wait of 15 to 30 seconds before forced entry into house with lights on); cert. denied, 445 U.S. 967, 100 S.Ct. 1659, 64 L.Ed.2d 244 (1980) United States v. (Louis) Smith, 171 U.S.App.D.C. 342, 520 F.2d 74 (1975) (after remand for findings, 524 F.2d 1287, upheld forced entry after announcement when exigent circumstances created by noises inside the apartment suggested destruction or concealment of evidence).
The majority does not address the trial judge’s finding of refusal of admittance because it concludes that the presence of the Uzi created exigent circumstances. See majority opinion at 462 n. 5 and 463. Nevertheless, the trial judge’s finding— that after five seconds followed by silence the police could reasonably conclude that they had been denied admittance — cannot be sustained on the record before us: five seconds would not generally afford the occupants sufficient time to open the door voluntarily. See, e.g., Masiello, supra, 115 U.S.App.D.C. at 58, 317 F.2d at 122 (refused admittance not restricted to affirmative refusal); United States v. James, 528 F.2d 999, 1017 (5th Cir.1976) (“[failure to respond within a reasonable time was tantamount to a refusal”; after 80 seconds and two announcements for the occupants to exit the house, police fired tear gas into the house); see also Griffin, supra, 618 A.2d at 122 (no authority cited in which delay of only 30 seconds in early morning hours sufficient in absence of some suspicious activity following arrival of police, or some other equivalent circumstance); Commonwealth v. Newman, 429 Pa. 441, 240 A.2d 795, 798 (Pa.1968) (20 seconds delay in answering door not refused admittance). In view of the evidence that the conversation of persons within the house stopped after the police knocked and announced, it was for the trial court to make findings on whether or not the occupants could have called out in response to the knock in so brief a time or whether they could only have been able to internalize the fact that someone was at the door. In the absence of any findings by the trial judge, the record here, as in Williams, does not support the conclusions that the police had waited long enough to decide that there was a *467constructive refusal to admit them. Silence for five seconds is not the same as evidence that people were moving with the possibility of escaping or obtaining the means to endanger the entering police officers.4
Hence, the question is whether the government has met its burden to show exigent circumstances. The instant case involves the presence of an automatic weapon which the police were informed was kept in the rafters in the basement of the house. However, there was nothing to suggest to the police that their presence had been detected by the persons inside the house before the police announced their presence by knocking on the front door. See, e.g., United States v. Spinelli, 848 F.2d 26, 29-80 (2d Cir.1988). The quick police entry was also not based on a concern about the destruction of evidence. See, e.g., United States v. Nabors, 901 F.2d 1351 (6th Cir.1990); United States v. Barrientos, 758 F.2d 1152 (7th Cir.1985), cert. denied, 474 U.S. 1062, 106 S.Ct. 810, 88 L.Ed.2d 785 (1986). Nor was there information that an armed guard would be sitting by the front window, or that more than one gun was inside the house much less that there was any illegal activity going on in the house. See, e.g., Williams, supra, 576 A.2d 700. After the police knocked, moreover, they did not hear any noise in response to their knock; rather, there was silence during the five seconds before the police forced their entry. Thus, as appellant points out, the finding of exigency was unsupported by facts providing a reasonable belief that the occupants of the house were attempting to destroy evidence or resisting apprehension. In that sense, the exigency found by the trial judge here is less than the exigency found in Williams, supra 576 A.2d 700, and the extent of the departure from the statutory requirements is greater since the police only knocked and announced on one occasion and then waited only five seconds.
The trial judge recognized that the presence of the Uzi inside the house was not by itself sufficient to create exigent circumstances without regard to the knock and announce requirements of the statute. The judge found that:
[the] officers did knock, did announce their authority and purpose in a way that was reasonably calculated for the people inside to hear it and to understand their purpose there. And the exigent circumstances presented at that moment therefore justified ... the immediate entry after the passage of only five seconds even if the passage of five seconds was not sufficient for them to have concluded that their entry was being denied.... And in my judgment these officers were acting reasonable [sic] in concluding after a very short passage of time that there was an exigent need to enter those premises by force immediate [sic] in order to avoid ... what was believed to be a serious risk of injury to the police or other citizens in the execution of the warrant.
Clearly, knowledge of the presence of an Uzi machine gun in the basement rafters did not suffice to give the police grounds to break into appellant’s home. See Nabors, supra, 901 F.2d at 1354 (although circumstances of a felon drug trafficker in possession of array of firearms who habitually wore a bulletproof vest, showed threat to police and others’ safety, and the need to conserve narcotics evidence justified forced entry moments after knocking and announcing, “[w]e do not hold ... that every time law enforcement personnel suspect that the subject of a search warrant pos*468sesses a firearm, a split-second announcement followed by a forced entry sufficiently complies with 18 U.S.C. § 3109”). The police had no information that the Uzi had ever been seen anywhere inside the house other than in the rafters in the basement. Nor is it the type of weapon that a person would carry on his or her person, like a pistol. That there was no response whatsoever to the knock at the door says almost nothing relevant in regard to exigent circumstances; the police did not hear anyone running and scurrying or any other sound, and the silence was not inconsistent with the occupants being startled or unable to respond to the front door so quickly. The trial judge’s findings in evaluating the effect of this silence on the overall circumstances was limited to finding that as a result of their knocking and announcing, “the officers were ... entirely reasonable in concluding that the people inside were then aware that the people outside were police officers there to execute a search warrant.”
Nevertheless, in view of the heightened capacity of an Uzi to inflict lethal injury, see majority opinion at 461 n. 2, the police had reason to be particularly concerned that they enter before anyone inside had an opportunity to inflict serious injury on officers or others. Fear of violence had caused the police to use the Emergency Response Team and to seek a nighttime warrant. The members of the Emergency Response Team thought that the Uzi was real, not an imitation. While the five second delay was insufficient to constitute a constructive refusal of entry, the police could reasonably conclude that the fact that they had knocked and announced their presence and purpose heightened a potentially dangerous situation. See Bonner, supra, 277 U.S.App.D.C. at 275-76, 874 F.2d at 825-26. The lights were on in the house and the police had heard people talking in the house. The information that a Uzi was in the house was only twenty-four hours old and the police had reason to believe that appellant contemplated committing another armed robbery, and thus was likely still to have the Uzi in his home. The police also had reason to believe that appellant had used a human hostage during a prior robbery with the Uzi. Contrary to appellant’s contention, the police were not simply acting on a mere “generalized belief” that the Uzi might be immediately available to appellant if they waited longer before entering the home. As the majority points out, see majority opinion at 463, supra, the trial judge relied on five circumstances as supporting a finding of exigent circumstances, including that the police had information that appellant made personal use of illegal drugs.
Under all of the circumstances, therefore, and consistent with our standard of review,5 this court is constrained to conclude that there was reasonable compliance with the knock and announce requirements of the statute in light of the exigent circumstances created thereafter. Cf. State v. Jeter, 30 Wash.App. 360, 634 P.2d 312, 314 (1981) (“a concern for police safety must be based upon prior knowledge or direct observation that the subject of the search keeps weapons and that such person has a known propensity to use them”); United States v. Cruz, 265 F.Supp. 15, 24 (W.D.Tex.1967) (upholding entry 15 seconds after knock and announce where police heard sounds and defendant “was dangerous man who always had a deadly weapon available in his residence” in view of apprehension of police that they might encounter a shoot-out); compare People v. Dumas, 9 Cal.3d 871, 109 Cal.Rptr. 304, 308, 512 P.2d 1208, 1212 (1973) (defendant known to answer door armed with a gun). Accordingly, I concur in the affirmance of the judgment.
. In that case, the police knocked and announced three times, on two separate occasions, and upon hearing footsteps running from the apartment, where cocaine was suspected of being sold, they used a battering ram to force open the door after a total of eleven to twelve seconds had passed. Id. at 272, 275, 874 F.2d at 822, 825. The court noted that “a few additional seconds’ delay clearly would have supported the conclusion that the officers had been refused admittance.” Id. at 276, 874 F.2d at 826. Nevertheless, the court concluded, on the basis of the five circumstances, that the officers had reasonably concluded they had been refused admittance. Id., 874 F.2d at 825. See United States v. DeLutis, 722 F.2d 902, 909 (1st Cir.1983) (upholding forced entry after 20 seconds delay) (and cases surveyed).

. The trial judge stated:
I would conclude that it is inappropriate for me as the reviewing judge to second guess by a matter of a split second here or there whether five seconds was sufficient or the police should have instead waited six seconds or ten seconds before reasonably concluding that they were not going to be allowed in. And in my judgment those distinctions are simply too fine to be made.
