DENECKE, Justice.
The issue is whether evidence should have been suppressed because it was allegedly obtained by officers entering premises without first knocking and announcing their presence and purpose.
The trial court denied defendants' motion to suppress the introduction of narcotics seized by the authorities. The defendants were convicted of the possession of narcotics. The Court of Appeals affirmed. State v. Darroch, 8 Or. App. 32, 492 P.2d 308 (1971). We granted the petition for review.
A federal undercover agent purchased a small quantity of hashish from the defendant Valentine. Later, the agent negotiated with Valentine and the defendant Darroch to buy a large quantity of hashish. The agent was told to come at noon to the apartment shared by the defendants to make the purchase. Based upon the agent's information, a search warrant for the apartment was obtained and delivered to a Corvallis police officer. This officer and other law enforcement officers went to the vicinity of the apartment.
The undercover agent was admitted to the apartment and was shown a five-pound box of hashish. He said he would go back to his car and get the money. He went out and according to his testimony left the apartment door so it appeared closed but the latch did not catch so the door could be opened easily.
The undercover agent informed the other officers there was five pounds of hashish inside and gave the signal to go in and arrest. One of the other officers, in plain clothes, pushed the door open and stepped inside with a drawn gun and announced he was a police officer. The other officers entered thereafter, including the one with the search warrant. Upon search the hashish, which was the subject of the motion to suppress, was found.
The state does not contend that the officers knocked or announced their presence by any means before they entered.
The defendants contend the entry was in violation of the Fourth and Fourteenth amendments to the Federal Constitution, Art. I, § 9 of the Oregon Constitution (unreasonable searches or seizures) and ORS 133.290.
We interpret Ker v. California, 374 U.S. 23, 83 S.Ct. 1623, 10 L.Ed.2d 726 (1963), as holding that an officer's failure to comply with the announcement requirement, when it is applicable, renders the ensuing search and seizure unreasonable and, therefore, in violation of the Fourth Amendment. The Oregon Court of Appeals in State v. Gassner, 6 Or. App. 452, 488 P.2d 822, 824 (1971), similarly interpreted Ker v. California, supra (374 U.S. 23).
The state contends that the entry was not in violation of the announcement requirement because the door was not latched and entry was obtained by ruse or subterfuge which is not in violation of the knock and announce rule. The Court of Appeals' opinion was based upon somewhat similar reasoning.
In order to determine the validity of these arguments it would be advantageous *86 to know the reasons underlying the rule prohibiting unannounced entries, whether the rule be constitutional or statutory.
The only opinion in Ker v. California, supra (374 U.S. 23, 83 S.Ct. 1623), that states reasons for the constitutional announcement rule is the dissent of Mr. Justice Brennan. He stated: "Innocent citizens should not suffer the shock, fright or embarrassment attendant upon an unannounced police intrusion." 374 U.S. at 57, 83 S.Ct. at 1642. The footnote to this statement elaborates:
"The importance of this consideration was aptly expressed long ago by Heath, J., in Ratcliffe v. Burton, 3 Bos. & Pul. 223, 230, 127 Eng.Rep. 123, 126-127 (1802):
"`The law of England, which is founded on reason, never authorizes such outrageous acts as the breaking open every door and lock in a man's house without any declaration of the authority under which it is done. Such conduct must tend to create fear and dismay, and breaches of the peace by provoking resistance. This doctrine would not only be attended with great mischief to the persons against whom process is issued, but to other persons also, since it must equally hold good in cases of process upon escape, where the party has taken refuge in the house of a stranger. * * *.'" 374 U.S. at 57, 83 S.Ct. at 1642.
In another part of the opinion Mr. Justice Brennan stated another purpose of the rule was "to minimize the hazards of the officers' dangerous calling." 374 U.S. at 58, 83 S.Ct. at 1642.
In Miller v. United States, 357 U.S. 301, 78 S.Ct. 1190, 2 L.Ed.2d 1332 (1958), the Court based its decision on its supervisory powers and not on the Constitution. It held that evidence had to be excluded because the entry by which the evidence was obtained was unlawful. Mr. Justice Brennan, for the majority, apparently believed the rule was rooted in "the reverence of the law for the individual's right of privacy in his house." 357 U.S. at 313, 78 S.Ct. at 1198.
Sabbath v. United States, 391 U.S. 585, 88 S.Ct. 1755, 20 L.Ed.2d 828 (1968), also excluded evidence because it was seized after an unannounced entry. It, too, was based upon the court's supervisory power. The Court cited Miller v. United States, supra (357 U.S. 301, 78 S.Ct. 1190), to the effect that the rule is based upon the protection of a householder's right of privacy in his home and for the protection of law enforcement officers.
We consider it unlikely that the Court would exclude good evidence upon the constitutional ground that exclusion was the only feasible method of preventing police officers from endangering their lives by making unannounced entries.
The California court more fully articulated one of the reasons advanced by Mr. Justice Brennan in his dissent in Ker v. California, supra (374 U.S. 23, 83 S.Ct. 1623), as a basis for the requirement of an announced entry. "The statute reflects more than concern for the rights of those accused of crime. It serves to preclude violent resistance to unexplained entries and to protect the security of innocent persons who may also be present on premises where an arrest is made." People v. Rosales, 68 Cal.2d 299, 66 Cal. Rptr. 1, 4-5, 437 P.2d 489, 492-493 (1968). Accord, Greven v. Superior Court of County of Santa Clara, 71 Cal.2d 287, 78 Cal. Rptr. 504, 455 P.2d 432, 436 (1969).
The Oregon Court of Appeals found the reasoning of the California Court persuasive and stated:
"The requirement of announcement and refusal prior to forcible entry exists primarily for the purposes of avoiding unnecessary violence and destruction of evidence  and not solely for the protection of privacy. Privacy is usually otherwise adequately protected under the Fourth Amendment to the United States Constitution and Oregon Constitution, *87 Art. I, § 9. * * *." State v. Mitchell, 5 Or. App. 230, 487 P.2d 1156, 1158 (1971).
To summarize, it appears that the announcement requirement has been given federal constitutional status (1) to protect persons who might be injured by violent resistance to unannounced entries by law enforcement officers, and (2) to protect the householder's right to privacy. This latter reason has been criticized, with some justification. Sonnenreich and Ebner, No-knock and Nonsense, an Alleged Constitutional Problem, 44 St. John's L.Rev. 626, 647 (1970).
It must be remembered that the police officers have the right to enter after they announce their presence and purpose and, if entry is denied, they have the right to force entry. The only right of privacy protected by the announcement requirement is the right to know who is entering, why he is entering, and a few seconds to prepare for his entry.
The "ruse and subterfuge" decisions provide some insight into the prevailing judicial views on the basic purposes of the announced entry requirement.
Leahy v. United States, 272 F.2d 487 (9th Cir.1960), was decided after Miller v. United States, supra (357 U.S. 301, 78 S.Ct. 1190). The facts in Leahy were that a federal revenue agent obtained an arrest warrant for defendant. The defendant was sought for evading a tax on wagering. The agent came to defendant's home and apparently knocked and stated he was an agent from the County Assessor's Office. Based upon this ruse, the agent gained admittance and got inside and arrested defendant. The court held the entry did not violate the "knock and announce" provisions of 18 U.S.C.A. § 3109 because there was no "breaking." The court further stated: "There is no constitutional mandate forbidding the use of deception in executing a valid arrest warrant." 272 F.2d at 490. The court observed that the officers had reason to believe that if they tried to arrest the defendant before gaining entry, there might have been a gun battle endangering life.
Jones v. United States, 113 U.S.App.D.C. 14, 304 F.2d 381 (1962), is not quite as clear. There, the officers had a search warrant for defendant's apartment. Defendant was suspected of the sale of narcotics. One of the officers knocked, the defendant said, "Who's there?"; the knocking officer said nothing; the defendant called out of the window to a "stranger" to call the janitor as there was someone at his door who would not go away. The "stranger" was another officer who got the janitor and had him knock on defendant's door. The defendant again asked who was there and the janitor replied, "the janitor." The defendant opened two of the locks and partly opened the door. The officer thrust his badge through the opening and said he had a search warrant. The defendant ran back through the apartment. The officer slipped off the night chain holding the door and entered and placed the defendant under arrest. A majority of the court, including then Judge Burger, held the entry was not contrary to 18 U.S.C. § 3109. The implication of the majority decision is that an entry is not unlawful if gained through "stealth or subterfuge."
The opinions in United States v. Beale, 436 F.2d 573 (5th Cir.1971), rehearing denied 445 F.2d 977 (5th Cir.1971), well illustrate how the "ruse and subterfuge" cases explain the prevailing views on the basic reasons for the announcement requirements. The facts were that the officers had a right to enter and arrest defendant, either by warrant or otherwise. The officers had a hotel manager knock on defendant's hotel room door and announce only the manager's presence. When the defendant opened the door, the officers entered and arrested him.
All the members of the panel agreed that the law before Sabbath v. United States, supra (391 U.S. 585, 88 S.Ct. 1755), was that an "entry secured by deception and without use of force" was not made unlawful *88 by 18 U.S.C. § 3109, the federal knock and announce statute. The majority held:
"Bearing all these considerations in mind, we are forced to the conclusion that Sabbath, by footnote 7, left undisturbed the existent distinction between entry where some force is employed and entry where force is not an element at all. We are not without doubts. The `fundamental values' and `ongoing development' to which Sabbath refers, 391 U.S. at 589, 88 S.Ct. 1755, include a broadening recognition of the citizen's right to privacy. Nevertheless we conclude that if entry by deception and wholly without application of force is to be brought within § 3109, it should be by the Supreme Court.
"We do not view federal constitutional standards as requiring a different result. * * *." 445 F.2d at 978.
Judge Tuttle dissented in the belief that the basic interest to be protected was the householder's right of privacy; therefore, it was immaterial whether the entry was made by ruse or by force:
"If the basic principle is, as I deem it to be, `the reverence of the law for the individual's right of privacy in his house,' then, it seems to me, that we should not hesitate to apply what to me appears to be a clear and logical extension of the doctrine announced in Sabbath, * * *." 445 F.2d at 979.
United States v. Syler, 430 F.2d 68 (7th Cir.1970), also decided subsequent to Sabbath v. United States, supra (391 U.S. 585, 88 S.Ct. 1755), is in accord with the majority in United States v. Beale, supra (436 F.2d 573).
The California courts, at least the Courts of Appeal, have also held that when an officer has a right to enter an unannounced entry gained by subterfuge is not unlawful. People v. Scott, 170 Cal. App.2d 446, 339 P.2d 162, cert. den. 361 U.S. 937, 80 S.Ct. 379, 4 L.Ed.2d 357 (1959); People v. Superior Court for County of Los Angeles, 5 Cal. App.3d 109, 84 Cal. Rptr. 778 (1970). The Ninth Circuit Court of Appeals so interpreted the California law. Ponce v. Craven, 409 F.2d 621, 626 (9th Cir.1969):
"It is clear from the language of section 844 that only if police resort to a breaking must they announce their purpose. The employment of a ruse which results in the occupant of a dwelling voluntarily opening the door and thereby allowing officers to enter without announcement of purpose, is not a breaking and, therefore, not violative of California arrest law. * * *."
The Oregon Court of Appeals has also previously held that an entry by stealth is not contrary to the announcement requirement. State v. Monteith, 4 Or. App. 90, 477 P.2d 224 (1970).
The author in Blakey, The Rule of Announcement and Unlawful Entry: Miller v. United States and Ker v. California, 112 Pa.L.Rev. 499, 516 (1964), was of the opinion that the "general rule" was that an entry to serve a lawful warrant gained by ruse or subterfuge was not unlawful.
He explains the significance of the "ruse and subterfuge cases":
"The pragmatic difference between these two theoretical approaches is brought sharply to the fore by the entry-by-trick-absent-force situation. If the interest to be protected is the occupant's initial right voluntarily to relinquish his right to be let alone, then the dissenters in Jones v. United States have have the best of the argument, and Leahy v. United States was wrongly decided. Leahy, of course, upheld outright misrepresentation; Jones upheld trick by implication. It is difficult to see how the distinction between the two is meaningful. The entries in both cases were ultimately by ruse. Meaningful consent played no part. But if it was unnecessary force which was at issue, then it is hard to argue with the thrust of Judge Orr's opinion in Leahy, and such cases as Gouled v. United States are quickly *89 placed in perspective. They involve ultimately questions going not to the manner of entry but the right to enter. When the right to enter exists, the manner of entry may be viewed in a different light. Ultimately, this is the burden of Judge Orr's opinion. So Justices Traynor and Weintraub likewise make clear in Maddox and Smith." 112 Pa.L.Rev. at 555.
The minority observed in United States v. Beale, supra (436 F.2d 573), that if the invasion of a householder's right to privacy alone is sufficient to invoke the federal constitutional and statutory protection, an entry by ruse or subterfuge must be unconstitutional and unlawful. An entry gained by a law enforcement officer posing as a county tax assessor, a hotel manager or janitor invades a householder's right to be free from an immediate, unannounced entry by a law enforcement officer, as much as a forced immediate entry by an unannounced law enforcement officer.
We have determined that in order for an otherwise lawful search and seizure to be in violation of the Federal Constitution because of the method of entry, the entry must violate both the interest in protecting persons from the harm that could come to them from the possibility of violence occurring because of unexplained entries and the interest of householders in the privacy of their home. An intrusion of one interest but not the other is not of sufficient substance to invoke the constitutional protection.
The method of entry in the present case does not intrude upon both of these interests. The defendants' right to the privacy of their home was temporarily invaded. The defendants did not intend to admit law enforcement officers; they only intended to have the undercover agent return; however, this is legally similar to the householder who consented to entry believing he was a county tax assessor, a janitor or a hotel manager. However, in the present case, as in the "ruse and subterfuge" cases, the possibility of violence because of a forced, unexplained entry was not present.
The evidence was not the product of an unreasonable search and seizure and not secured in violation of the Federal Constitution.
The defendants also contend the seizure was contrary to § 9, Art. I, of the Oregon Constitution. Section 9 provides, in part: "No law shall violate the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable search, or seizure." In interpreting the Oregon Constitution the decisions of the United States Supreme Court, of course, are not authoritative.
We are of the opinion that an otherwise lawful search and seizure accomplished by an entry which was made without an announcement of presence and purpose is not an unreasonable search and seizure within the meaning of the Oregon Constitution. We reach this conclusion because of our opinion that the interest of the momentary protection of the privacy of the householder and the interest in protecting innocent persons from the violence that may stem from an unannounced entry are not of sufficient substance to rise to constitutional stature and require the exclusion of otherwise competent evidence.
The Oregon Court of Appeals was of a similar opinion. State v. Gassner, supra (488 P.2d at 824). The court quoted from Sonnenreich and Ebner, supra (44 St. John's L.Rev. at 646-647):
"Proponents of a strict announcement requirement have created a constitutional certainty from a common-law uncertainty * * *. To elevate the announcement rule to a constitutional requirement in 1963 was probably historically unsound. To premise it upon a vague right of privacy, rather than on the avoidance of potential violence was a further departure from precedent. * * *."
The defendants also contend the entry was made contrary to the Oregon *90 knock and announce statute, ORS 133.290.[1] Assuming, without in any way deciding, that the entry in this case was in violation of this statute, the evidence secured by such an entry is not to be excluded.
The reason for the federal rule excluding evidence obtained in violation of the Federal Constitution was settled in Linkletter v. Walker, 381 U.S. 618, 85 S.Ct. 1731, 14 L.Ed.2d 601 (1965):
"* * * Mapp [Mapp v. Ohio, 367 U.S. 643, 81 S.Ct. 1684, 6 L.Ed.2d 1081] had as its prime purpose the enforcement of the Fourth Amendment through the inclusion of the exclusionary rule within its rights. This, it was found, was the only effective deterrent to lawless police action. Indeed, all of the cases since Wolf [Wolf v. Colorado, 338 U.S. 25, 69 S.Ct. 1359, 93 L.Ed. 1782] requiring the exclusion of illegal evidence have been based on the necessity for an effective deterrent to illegal police action. * * *.
"* * * In rejecting the Wolf doctrine as to the exclusionary rule the purpose was to deter the lawless action of the police and to effectively enforce the Fourth Amendment. * * *." 381 U.S. at 636-637, 85 S.Ct. at 1741-1742.
After years of the exclusionary rule some thoughtful observers are doubtful that the exclusionary rule has accomplished its purpose, and even more doubtful whether the cost brought about by excluding good evidence was worth the goal. Burger, Who Will Watch the Watchman?, 14 Am.U.L.Rev. 1 (1964); Wright, Must the Criminal Go Free if the Constable Blunders?, 50 Tex.L.Rev. 736, 741 (1972); Oaks, Studying the Exclusionary Rule in Search and Seizure, 37 Chi.L.Rev. 665 (1970).
There is no evidence in the record or of which we can take judicial notice that law enforcement officers of Oregon are perniciously disobeying the knock and announce statute. On the contrary, police self-interest should dissuade police from making entries in violation of the statute. The United States Supreme Court, as previously stated, has reasoned on several occasions that one reason for the announcement requirement is to avoid the hazard to law enforcement officers that accompanies an unannounced forcible entry. Sabbath v. United States, supra (391 U.S. 585, 88 S.Ct. 1755), and Mr. Justice Brennan's dissent in Ker v. California, supra (374 U.S. at 46, 83 S.Ct. 1623).
This court in State v. Laundy, 103 Or. 443, 494, 204 P. 958, 206 P. 290 (1922), adopted the principle that evidence secured in violation of Art. I, § 9, of the Oregon Constitution would be excluded from evidence. We were not bound by the decisions of the United States Supreme Court; however, we chose to follow Weeks v. United States, 232 U.S. 383, 34 S.Ct. 341, 58 L.Ed. 652, L.R.A. 1915B, 834, Ann.Cas. 1915C 1177 (1914), and exclude evidence seized in violation of the search and seizure provision of the Oregon Constitution.
We have never excluded evidence because it was obtained in violation of a statute, as contrasted with a violation of the Federal or State Constitutions. In State v. Shipley, 232 Or. 354, 360-362, 375 P.2d 237 (1962), a majority of this court refused to exclude a confession although it had been obtained as a result of a detention which was admittedly in violation of ORS 133.550. That statute requires an arresting officer to take his prisoner before a magistrate without delay. The magistrate must inform the prisoner of his right to the aid of counsel before any further proceedings are had. ORS 133.610.
In addition to these specific reasons why the evidence should not be excluded, we stated a general policy:
"* * * [W]e continue to regard a trial as a search for the truth and, therefore, competent evidence should never be *91 excluded except for the most compelling reason. * * *." State Forester v. Umpqua River Navigation Co., 258 Or. 10, 26, 478 P.2d 631, 639 (1970).
Affirmed.
O'CONNELL, Chief Justice (dissenting).
Although I have some difficulty in seeing the knock and announce rule as having constitutional proportions, the U.S. Supreme Court has so evaluated it and therefore I must start with that premise.
The premise, stated broadly, is that the requirement of the Fourth Amendment that a search be reasonable is not met unless the officer making the search first knock and then announce his authority and purpose. Since the rule is derived from the Fourth Amendment it necessarily must be explained in terms of the interest of privacy which the amendment purports to protect. Armed with a valid warrant the officer is privileged to invade the occupant's enclave of privacy once a proper entry is made. However, at the threshold of the entry the officer must make his presence and mission known so that he does not make the encounter with the occupant any more offensive to his dignity than is necessary. If this is the interest the courts are charged with protecting, I do not see how it can be said that the requirement of knocking and announcing can be obviated through ruse, subterfuge or deception, as some of the cases cited in the principal opinion have held.
It is strange doctrine to say that a man has a right to know who seeks entry to his home, unless he can be cheated out of it by the agents of government. In circumstances where the officer's safety would be endangered by an announcement of his purpose, he should be permitted to enter without making it. But short of that, the occupant should be entitled to have warning of the nature of the business which brings the visitor to his door. It may be argued that this treats too delicately the owner's interest in privacy. If this is so, then there is no reason to give the knock and announce rule constitutional status. But as long as we bring the rule under the Fourth Amendment it should be applied consistent with the purpose it is intended to serve.
Even if the ruse exception were to be recognized by us, the facts in the present case do not bring it within the exception. The officers who entered after Holm had departed did not gain entrance as a result of anything that had any relation to Holm's departure. Tested by any theory advanced for the knock and announce rule, the entry made by the officers in this case was no different than if Holm had never left the room.
Even if the rule is regarded as being founded in part upon the theory that it will tend to avoid unnecessary violence, the circumstances of entry in the present case created as much danger as if Holm had not taken part in the episode.
I wish to incorporate in this opinion the dissenting opinion of Judge Fort when this case was decided in the Court of Appeals.
McALLISTER, J., joins in this dissent.
