The defendant appeals from a conviction of receiving stolen goods. The stolen goods, diamonds, were found when a police officer searched the defendant’s person; and the validity of that search is the sole issue in this appeal.
The search took place in Holyoke on a November evening in 1980. Two Holyoke police officers on routine patrol pulled into a small shopping center and parked next to a red Camaro automobile in front of a liquor store. From prior official contacts the police recognized one Thurston sitting in the front passenger *686 seat. No one else was in the automobile. The police knew Thurston was not of drinking age. Through the window one of the officers saw a handrolled cigarette with twisted ends on the console between the front seats. The officer had prior experience and training in narcotics investigation. He recognized the cigarette as likely to be a “joint,” or marihuana cigarette. He asked Thurston what was in the cigarette. Thurston denied ownership of it. The officer reached inside, took the cigarette, smelled it, and confirmed that it contained marihuana. Next to the cigarette, also on the console, was a bean bag ashtray with quarter inch long stubs, which the officer recognized to be “roaches,” or smoked marihuana cigarettes. 1 Thurston exited from the automobile and was searched for further marihuana or other drugs. None was found.
At that point the driver, the defendant Skea, returned to the vehicle. He also was well known to the officers, having been arrested many times in the past. The officers asked him if the joint was his. Skea replied, “Give me a break.” The officers searched Skea’s pockets looking for further marihuana or other controlled substances. In a zippered breast pocket of Skea’s jacket was a cellophane envelope. It contained what appeared to be four diamonds. 2 Skea asserted that he had purchased them two weeks before for fifty dollars. He was asked if he had a bill of sale, to which he replied no. He was asked whom he bought the diamonds from, and he answered that he did not know his name.
The police retained the packet of diamonds for further investigation with Skea’s consent. 3 The officers also decided not to *687 arrest Skea and Thurston for possession of marihuana, and instead they destroyed the joint and the roaches by trampling them on the ground. This was in accordance with their informal policy not to arrest for possession of small amounts of marihuana unless a search revealed further or more serious drugs. Further investigation revealed that the diamonds were in fact stolen,* ** 4 and Skea was arrested several weeks later. 5
The defendant filed a pretrial motion to suppress evidence of the diamonds, contending that the search was without a warrant, that it did not fall within any recognized exception to the warrant requirement, and that it was not justified by stop and frisk principles enunciated in
Terry
v.
Ohio,
The second point is without merit. The policemen’s observations through the windows of the automobile, in a public parking lot, by themselves involved no search.
Commonwealth
v.
Cavanaugh,
Under those governing principles, the panel are in agreement that the seizure and examination of the marihuana cigarette lying on the console of the automobile was constitutionally valid. The examination confirmed that it was marihuana. Thurston’s denial of ownership, the fact that Skea was the only other person to whom the cigarette could plausibly belong, and his (Skea’s) statement, “Give me a break,” which could properly be taken as an admission of ownership, all combined to give the police probable cause both to arrest Skea (see G. L. *690 c. 94C, § 41) and to search him for additional marihuana or other controlled substances. 8
The defendant is correct, however, in arguing that the search-incident-to-arrest rationale does not fit with the fact that the defendant was released after the search and was not taken into police custody until several weeks thereafter. Detentions for frisking, questioning, routine traffic stops, and the like, where the detainee is released after the police business is transacted, are treated as ‘“seizures’ of the person,” subject to Fourth Amendment scrutiny (see
Terry
v.
Ohio, 392
U.S. at 16-17;
Cupp
v.
Murphy,
The defendant argues that this should be the end of the matter. The search, he argues, being warrantless, was presumptively unconstitutional,
Mincey
v.
Arizona,
That result, however, is disturbing because of the fact that the police officers seem to have acted throughout the episode with both reasonableness and restraint. Their actions were restrained in that they were willing to overlook simple possession of a small amount of marihuana, and again in that they withheld arrest until they ascertained that the diamonds were in fact stolen property. Their actions were reasonable in the sense that they acted on probable cause and exigent circumstances in making the search for additional marihuana. The circumstances were “exigent” in the accepted sense of that word: there was a real “likelihood of imminent loss of the evidence,”
Commonwealth
v.
Tarver,
Must we, then, conclude that, despite having probable cause to believe Skea was in possession of contraband, and despite the unanticipated exigency, the police violated Skea’s constitutional right of privacy by searching to recover any hidden contraband?
Katz
v.
United States, supra,
relied on heavily by Skea, is frequently read as suggesting that probable cause and exigency may not be enough to justify a warrantless search: that, in addition, the search must fall within one of several enumerated groups or classes to avoid Fourth Amendment invalidity. “[Sjearches conducted outside the judicial process, without prior approval by judge or magistrate, are per se unreasonable under the Fourth Amendment — subject only to a few specifically established and well-delineated exceptions” of which three were there listed.
11
It is suggested that the police were not caught in such a dilemma: that, having probable cause to arrest Skea, they could have effected a valid search of his person by simply placing him under arrest. Doubtless that would have been the legally safer course. The suggestion is nonetheless odious, because it counsels a greater intrusion on the suspect’s liberty, a formal arrest, to justify the lesser intrusion of a search, see 2 LaFave, Search and Seizure § 5.4, at 344 (1978), and thus distorts the intended protections of the Fourth Amendment into an instrument of oppression. 14 A requirement of a validating arrest cannot *695 plausibly be thought to serve the purpose of deterring searches, where it is settled (by the Rawlings case, supra) that the search incident to an arrest may validly precede the arrest. Under that principle, it cannot be said that Skea’s constitutional rights were violated when he was first searched; if he had been arrested immediately afterwards (if not on probable cause with respect to the diamonds then on the basis of the single marihuana cigarette), no question could now arise as to the constitutional validity of the search. It is thus apparent that the defendant is contending for a nonsense proposition: that his constitutional rights were violated at the moment when the police decided not to arrest him and instead let him go.
The possibility of a validating arrest, moreover, would not resolve the dilemma in every case. It is doubtless usual that the same information that constitutes probable cause to search also establishes probable cause to arrest; but there is no necessary correlation between the two. For example, the facts known to the police officers may indicate that an innocent person has been given counterfeit bills in his change or may háve purchased stolen merchandise from an antique dealer. A shoplifter or pickpocket, suspecting he is under surveillance, may stash the loot in an innocent person’s pocket or purse, or a child or person known to the police not to be responsible for his actions may be thought to be in possession of narcotics or other contraband. In each of these cases the police would lack probable cause to arrest (i.e., to think the person guilty of a crime) but would have probable cause to search for the contraband.
It has never been doubted that probable cause and exigent circumstances give constitutional justification for a warrantless search of a residence. The principle is recognized in such cases as
Johnson
v.
United States,
It may reasonably be objected that, if probable cause and exigent circumstances, without an arrest, may justify the search of a person, then such an exception would by now have found articulation in the Federal cases. To this objection there are two answers. First, the situation rarely arises in which the rationale of probable cause and exigent circumstances must be pressed into service. As has been observed, the same probable cause that justifies a search normally justifies an arrest as well. Where contraband is found, an arrest will generally follow. Where it is not, the suspect is either released to go on his way, nothing more being heard of the matter; or, if he is arrested, no issue is later made of the search precisely because it uncovered no contraband or other matter to be offered in evidence. In either case, the validity of the search can be raised in a private civil action, see
United States
v.
Ross,
The second answer is that, in those rare cases that have arisen, the validity of the search has in fact been upheld on exigency analysis. In
Cupp
v.
Murphy,
Substantially the same rationale has been adopted in recent narcotics cases involving luggage seizures. In
United States
v.
Place,
Concededly, the examples are few of cases where searches of or seizures from persons have been justified on the basis of
*700
probable cause and exigent circumstances. The likely reason is, as explained above, that in the great majority of cases the police either find nothing or effect an arrest. But the general principle is implicitly recognized in numerous decisions, almost in passing. See, e.g.,
Florida
v.
Royer,
*701
On general principles, a search justified by probable cause to search and exigent circumstances must be limited in scope to those areas of the person and his clothing which could reasonably be thought to contain the items sought. See
Chimel
v.
California,
Here, because search was for marihuana or other controlled substances, its permissible scope was necessarily broad.
Commonwealth
v.
Cantalupo,
Judgment affirmed.
Notes
Neither the testimony nor the judge’s findings indicate whether the officer first saw the roaches before or after reaching into the automobile to take the joint. From the fact that the ashtray was in plain view on the console next to (“six or eight inches from”) the joint, the finder of fact could properly draw an inference that the roaches were visible to the officer from the outset.
Three were in fact diamonds. One turned out to be a rhinestone.
Skea does not contest the validity of the retention of the diamonds, as opposed to the validity of the search that disclosed them. The judge found that Skea had consented to the police keeping the diamonds for inquiry, and there was evidence that warranted that finding. Alternatively, it could
*687
have been found that the police had probable cause to believe the diamonds may have been stolen. There was testimony that the previous evening one of the two officers had been dispatcher; that there had been a mugging in which a diamond ring was stolen; that Skea’s companion, Thurston, had been in the vicinity of the mugging and had been brought to the victim for identification (without, so far as the record discloses, a positive result); and that there was another unsolved diamond theft from two days before. These facts, coupled with the unusualness of a young man casually carrying around diamonds in his pocket, the fact that Skea could produce no bill of sale or identify the person from whom he claimed to have bought them, and the potential connection between youthful drug use and thievery, all would combine “to warrant a person of reasonable caution in believing that the defendant had committed ... a crime . . . .”
Commonwealth
v.
Gullick,
The packet of diamonds did nbt include the one from the ring stolen in the mugging the night before. Rather, the entire packet with its contents had been stolen in a housebreak earlier in the day of the search. Four diamonds had been given to the victim’s husband by his employer in recognition of forty years of service. The victim had lost one diamond when she accidentally spilled the contents of the packet. Without knowing for certain what it was, the victim had also added the rhinestone (readily differentiated because of its gilt base) intending to bring all to a jeweler for appraisal and sale.
The record does not disclose whether Thurston was later arrested or charged in connection with the diamonds.
Texas v. Brown, supra, was a plurality decision, but there was no disagreement on the Court as to the propriety of the seizure of the suspected contraband (there, tied, deflated balloons containing heroin). See id., at 746-747 (Powell, J., concurring, joined by Blackmun, J.) and 750 (Stevens, J., concurring, joined by Brennan and Marshall, JJ.). All other Justices joined in the plurality decision.
Thomas
v.
Superior Court,
It is widely accepted that the discovery of some controlled substances gives probable cause to search for additional controlled substances in the vicinity. See, e.g.,
Commonwealth
v.
Blatz, 9
Mass. App. Ct. 603, 604-605 (1980);
United States
v.
Faulkner,
“It is scarcely open to doubt that the danger to an officer is far greater in the case of the extended exposure which follows the taking of a suspect into custody and transporting him to the police station than in the case of the relatively fleeting contact resulting from the typical Terry-type stop. This is an adequate basis for treating all custodial arrests alike for purposes of search justification .... [W]e hold that in the case of a lawful custodial arrest a full search of the person is not only an exception to the warrant requirement of the Fourth Amendment, but is also a ‘reasonable’ search under that Amendment.” Ibid.
“To constitute an arrest, ‘[1] there must be an actual or constructive seizure or detention of the person, [2] performed with the intention to effect an arrest and [3] so understood by the person detained. . . .’”
Massachusetts Gen. Hosp.
v.
Revere,
The Katz case did not state what the specifically established exceptions were, but cited to cases sustaining warrantless searches of cars stopped on the open highway, a house entered in hot pursuit of a fleeing felon, and a person placed under arrest. Id. at 357 n. 19.
Texas
v.
Brown, supra,
See
Trupiano
v.
United States,
In
People
v.
Simon,
“Thus, if the officer is entitled to make an arrest on the basis of information available to him before he searches, and as an incident to that arrest is entitled to make a reasonable search of the person arrested . . ., there is nothing unreasonable in his conduct if he makes the search before instead of after the arrest. In fact, if the person searched is innocent and the search convinces the officer that his reasonable belief to the contrary is erroneous, it is to the advantage of the person searched not to be arrested. On the other hand, if he is not innocent or the search does not establish his innocence, the security of his person, house, papers, or effects suffers no more from a search preceding his arrest than it would from the same search following it.”
The possibility of a civil action for damages highlights the conceptual problems inherent in the view that probable cause without an arrest cannot justify a warrantless search of a person. If a police officer has probable cause to believe a suspect on the street is carrying, say, heroin, it is clear from
Rawlings
that he is not required first to arrest, then to search. He may instead begin with the search (see
Sibron
v.
New York,
One such case was
Commonwealth
v.
Cantalupo,
In the
Chadwick
case itself the constitutional justification for the seizure of the footlocker was not in issue because its owners were arrested and the footlocker seized incident to the arrests.
We have found only one case which, on comparable facts, reached a contrary result. In
People
v.
Evans,
Correctly, the defendant does not argue that the diamonds were inadmissible under G. L. c. 276, § 1. That statute was enacted in response to
United States
v.
Robinson, supra,
which established that a search incident to a valid custodial arrest was not limited by probable cause to believe the search would uncover weapons, contraband, or evidence of the crime which furnished the basis for the arrest.
