OPINION OF THE COURT
These appeals present the question of when, if ever, a police officer may detain at gunpoint an individual whom he reasonably suspects of having committed a crime. Our determination necessarily depends upon a delicate balance between the individual’s right to personal liberty and society’s legitimate expectation that its police officers may carry out their official functions free from unreasonable risk of death or personal harm. We turn first to a review of the pertinent facts.
At aрproximately 9:00 p.m. on August 10, 1977, Joseph Baxter was alone at a Hess gas station on Peninsula Boulevard in Hempstead, New York. Baxter, the assistant manager of the station, was sitting at its middle island when he observed two men approaching him on foot. When the men
Immediately after he activated the alarm, Baxter’s fears were realized. The man who had asked about the repair of the tire now announced a holdup and demanded that Baxter surrender his money. After taking some $35, he instructed Baxter to walk to the sales office, warning him that "I have a gun. If there is [sic] any cops around I will blow your head off.”
When they reached the door of the office, the man asked for additional money and searched Baxter’s pockets. He discovered the transmitter, and when Baxter would not explain the nature of the device, the man repeated his threat, saying that "There had better not be any cops around or I will blow your head off.” Both perpetrators then fled on foot heading southbound on Peninsula Boulevard.
Less than a minute aftеr their departure, Police Officer Alexander Zackavich arrived on the scene in a patrol car. He had been driving alone in the area when he received a radio report of a robbery in progress at the Hess station. The officer drove into the station and observed Baxter running toward him waving his arms. Baxter, whom the officer recognized as the station’s manager, urgently signaled him to proceed around the corner onto Taft Avenue which was a quarter of a block south of the station. In response to thosе signals and without stopping his car, Zackavich immediately drove out of the station and around the corner onto Taft Avenue.
Upon making that turn, the officer observed a vehicle, approximately 150 feet ahead, proceeding away from Peninsula Boulevard. He saw no other automobile and no pedestrians on the street. He turned on the patrol car’s flashing lights and sounded its horn in an effort to stop the other vehicle, but it continued moving, turning left at the next intersection. The officer pursued, now blaring his siren in an attempt tо compel
Officer Zackavich brought his radio car to a stop directly behind the subject vehicle. He then exited his car carrying a shotgun and approached the other vehicle on its driver’s side, confronting its two occupants who were later identified as defendants Finlayson and Blades. The officer pointed the shotgun at them and ordered them to place their hands on the dashboard of the car. When they complied, he used the radio he was carrying on his belt to call for a description of the perpetrators.
By this time, Baxter had described the robbers to other officers who had arrived at the scene. The descriptions, which included the perpetrators’ sex, race, height, weight, facial appearance and clothing, were transmitted to Officer Zackavich. Upon determining that the descriptions matched the occupants of the car, the officer told them that they were under arrest for the robbery at the Hess station. He advised them of their constitutional (Miranda) rights and ordered them to remain as they were while he radioed for assistance. When other police units arrived, the defendants were removed from the vehicle, frisked, handcuffed, and placed in patrol cars. Officers then discovered the proceeds of the robbery secreted under the front seat of the defendants’ vehicle. No weapon was found either in the car or on the persons of the defendants.
Later that evening, a lineup was conducted and Baxter identified both defendants as the perpetrators of the robbery. Subsequently, after having been advised again of his constitutional rights, defendant Finlayson confessed to the commission of the crime.
The defendants were jointly indicted for robbery in the second degree and grand larceny in the third degree. Both moved to suppress the proceeds of the crime as well as the potential identification testimony of the complainant Joseph Baxter. Defendant Finlayson also sought suppression of his statеments to the police.
A hearing was held on the motions to suppress. The crux of
Our analysis begins with the observation that Officer Zackavich did not have probable cause to justify an immediate arrest when he first encountered the defendants on the street, since, at that moment, he lacked sufficient information regarding the identity of the perpetrators. The absence of probable cause, however, is not dispositive of the outcome here since probable cause is not a necessary predicate for all contact between police and the citizenry in the course of a criminal investigation. (See United States v Mendenhall,
The reasonableness standard contemplates and permits a flexible set of escalating police responses, provided only that they remain reasonably related in scope and intensity to the information the officer initially has, and to the information he gathers as his encounter with the citizen unfolds. (Cf. People v De Bour,
Among the levels identified in De Bour (supra) and elsewhere (e.g., CPL 140.50, subd 1; Brown v Texas,
The officer received and was entitled to rely upon the radio report of a robbery in progress at the station. (Cf. People v Lypka,
At the hearing, counsel attempted to establish that there were escape routes—alleyways and the like—which could well have accommodated the perpetrators. It was possible that the actual perpetrators had taken one of those routes and that the occupants of the lone vehicle on the street were innocent of any wrongdoing. Yet in dealing with the standard of reasonable suspicion, as with the higher standard of probable cause, we do not require certainty. (See People v McLaurin,
In view of our holding that the defendants’ cаr was properly stopped, we are next obliged to determine whether the scope and intensity of the ensuing police conduct remained reasonably related to the circumstances surrounding the encounter. Clearly, a stop which is justified at its inception may be rendered unlawful by unwarranted police action taken as the confrontation progresses. (Terry v Ohio, supra, p 18; Go-Bart Co. v United States,
At the outset, we note that the Court of Appeals has recently rejected the notion that whenever an officer approaches a citizen with weapon drawn he effects an arrest supportable only by probable cause. (People v Chestnut,
An officer may take appropriate self-protective measures when he lawfully confronts an individual and reasonably believes him to be armed or otherwise dangerous to the officer
Thus, for example, if an officer were to draw his weapon against an individual suspected only of shoplifting or some other petty offense, the intensity of the confrontation, in the absence of any independent indication of danger, would be raised to a levеl well beyond that which could be justified as reasonably related to the surrounding circumstances. Such an encounter would then be deemed an arrest supportable only by probable cause. (Cf. People v Cantor,
In essence, then, we speak of two separate areas of knowledge and belief. The first involves information pointing to the individual as the perpetrator of the crime. This establishes the predicate for the initial police intrusion upon the individual’s liberty, and it is fundamental that no frisk or gunpoint approach may ever be sanctioned in the absence of a sufficient predicate entitling the officer to stop and detain the individual in the first instance. (Cf. People v Earl,
Moreover, in assessing these confrontations, it is absolutely essential that courts reach determinations based not upon some abstract or illusory notion of what police-citizen encounters ought to be like in an ideal world but upon an objective evaluation of the realities of the encounter as it occurred. (See Elkins v United States,
In the case at bar, Officer Zackavich found himself approaching a vehicle occupied by two men whom he reasonably suspected of having committed a robbery. He was alone. It was nighttime. The encounter was taking place in a deserted industrial area. The crime under investigation was a holdup at a gas station. Although conceivably such a crime could have been perpetrated by individuals who were unarmed, that was nоt a likely possibility and it was reasonable for the
Simply put, then, Officer Zackavich had a reasonable basis to believe that he was coming face-to-face with two armed robbers who were unwillingly submitting to contact with him after having unsuccessfully attempted to evade him. Under these circumstances, the officer was justified in fearing that any request for information might well be answered with a bullet. (People v Rivera,
Under the totality of the circumstances, we hold that Officer Zackavich’s conduct was entirely proper. He had reasonable suspicion sufficient to support the stop of the defendants’ car in the first instance. He had reasonable grounds to believe that the defendants were armed and dangerous and was therefore justified in briefly detaining them at gunpoint as they sat in their car. And, upon receiving the descriptions, he had probable cause to place the defendants under arrest.
Significantly, the very same result is required when the case is measured against the policy considerations underlying the very exclusionary rule which the defendants seek to invoke. Among the primary purposes of the rule is to deter official lawlessness by denying to the government the fruits of its own misconduct. (Cf. United States v Calandra, 414 US
The application of the exclusionary rule presupposes the existence of unlawful or improper police conduct. In this case, however, we are unable to identify anything that Officer Zackavich did that was wrong or unreasonable. Clearly, he was duty bound to stop the defendants’ vehicle to make inquiry. And wе do not perceive that any constitutional provision would require a lone officer to approach two suspected armed robbers who are seated in a car without drawing his own weapon. Were it otherwise, policemen would be compelled to choose whether, on the one hand, to forego their sworn duty to uphold the law or, on the other hand, to face serious and unnecessary risk of death or personal harm. The police officer, in the instant circumstances, acted promрtly and efficiently in fulfilling his responsibilities as a law enforcement officer. The fact that he did so in a prudent and reasonable manner, with proper regard for his personal safety, did not constitute a violation of defendants’ constitutional rights. As the court warned in Terry v Ohio (
Society cannot and should not demand of its policemen that, in fulfilling their responsibilities as law enforcement officers, they needlessly and unreasonably expose themselves to serious injury or death. Certainly, nothing in the Constitution requires that they do, for, as the Supreme Court observed when it first made the exclusionary rule binding on the States, "[t]here is no war between the Constitution and common sense.” (Mapp v Ohio,
Lazer, Gibbons and Margett, JJ., concur.
Two judgments (one as to each defendant) of the County Court, Nassau County, both rendered January 26, 1979, affirmed.
This case is remitted to the County Court, Nassau County, for further proceedings pursuant to CPL 460.50 (subd 5).
Notes
. The District Attorney represented to the court that, on the morning after the robbery, a discarded but fully loaded .38 caliber revolver was found in front of 96 Taft Avenue. The prosecutor conceded that he was unable to connect the weapon to the defendants and indicated to the court that he would take steps to see that his witnesses would make no mention of the gun during trial.
. Dunaway v New York (
We do not read Dunaway as holding or suggesting that an officer may not briefly detain and question an individual in a public place on less than probable cause.
. Indeed the language of some cases in the area seems to suggest that, for Fourth Amendment purposes, a gunpoint approach would actually be less intrusive than the laying on of hands involved in a physical seizure and pat-down frisk. (See People v Stewart,
