Opinion
In view of the fact that the arresting officers were dressed in plainclothes and using an unmarked vehicle when they forced entry into defendant’s residence at night, can we hold that the requirements of section 844 of the Penal Code had been met?
We have heretofore identified the essential requirements of section 844 as (1) identification of themselves by the police; (2) explanation of their purpose; and (3) demand for entry.

v.
Superior Court,
Literal compliance is not a factor here, and hence requires no comment.
Substantial compliance expresses a rule of interpretation which derives from general maxims of equity—that substance governs over form, that no one is required to perform an idle act. (Civ. Code, §§ 3528, 3532.) Hence if the essence of a requirement has been met, or if its performance would be superfluous, then the law holds that the requirement has been substantially complied with. The application of the rule may be seen in
People
v.
Cockrell,
Our original opinion assumed that those inside the residence knew that their visitors were police officers and therefore identification by the police would have been a useless act. It is undisputed that (1) entry was forced into an occupied residence; (2) during the nighttime; (3) by police officers not in uniform; (4) who had driven up to the residence in an unmarked vehicle. Under these circumstances, can it be assumed with reasonable certainty that those inside the house knew their visitors were peace officers engaged in the performance of their duties and hence official identification by the visitors would have been an idle gesture? The only direct testimony on this subject was to the contrary, for Mrs. Boone testified *507 that she thought the men running toward her house were intruders or burglars. We are not required to accept her testimony, and we would not do so if it were contradicted by circumstances which clearly indicated its implausibility. For example, if uniformed officers had arrived on the scene in a marked police vehicle, with sirens wailing, and red lights flashing, then we would give little credence to statements of those inside that they did not know their visitors were police. If such a trumpeting of status had occurred we could assume with confidence that those inside the house knew their visitors were police officers engaged in law enforcement activities and hence further identification by the police would have been a useless act.
But at bench no external symbols or trappings identified the men who forced entry into the premises as peace officers engaged in the performance of their official duties, and from the circumstances we cannot be reasonably certain that those inside knew that those outside who sought to enter were police. Hence the requirement for identification still carried meaning. The practical dangers attached to forcible intrusion by peace officers unidentified as such have been summarized by Mr. Justice Brennan, dissenting, in
Ker
v.
California,
On the facts of this case we conclude that identification by the police *508 would not have been a useless act and that hence requirements of section 844 had not been substantially met.
But the requirements of section 844 need not always be met. Where exigent' circumstances make an immediate entry imperative, compliance with the statute may be excused. Exigent circumstances have not been comprehensively defined, but they include instances where those inside are likely to be armed, or likely to attempt escape, or likely to commit further crimes of violence if entry is sought in the statutory manner. In such instances the need to neutralize specific hazards excuses compliance with the statute and justifies' forcible entry without identification, demand, and statement of purpose. Exigent circumstances may also include instances which involve pending destruction of evidence. The extent to which a prospective danger of such destruction will justify an unannounced entry is not entirely clear

We originally concluded that compliance with section 844 was excused because of attempted destruction of evidence, citing

In reaching this conclusion we have been influenced by the need for added caution by the police in carrying out forcible intrusions into residences during the hours of darkness. Such nighttime intrusions are disfavored under California law. Section 1533 of the Penal Code, dealing with the service of search warrants, requires the warrant to be served during the daytime unless, on a showing of good cause, the magistrate has inserted a direction in the warrant that it may be served during the night. The comparability of the Penal Code section covering forcible entry to make a search (§ 1531) with that covering forcible entry to make an arrest (§ 844) has been noted by the Supreme Court.

v.
Superior Court,
We conclude that the requirements of section 844 were neither substantially complied with nor were they excused. Consequently, the narcotics seized during the arrest were inadmissible, and the judgment of conviction must be, and hereby is, reversed.
Roth, P. J., and Wright, J., concurred.
Respondent’s petition for a hearing by the Supreme Court was denied February 5, 1970. McComb, J., was of the opinion that the petition should be granted.
