Under People v. DeBour, a 1976 New York Court of Appeals decision, police-citizen encounters in New York fall into four escalating levels, each requiring a higher degree of justification before an officer can act. The four levels of police encounters set out in People v. DeBour are a request for information, the common-law right of inquiry, a forcible stop and frisk, and an arrest. The justification climbs with each step: an objective credible reason, then a founded suspicion of criminal activity, then reasonable suspicion, and finally probable cause. New York applies this framework even to casual questioning that federal law leaves unregulated, which is why the level of the encounter usually decides whether evidence stays in a case or gets thrown out.1New York State Unified Court System. People v De Bour
Level One: Request for Information
An officer needs only an “objective credible reason” to approach you, and that reason doesn’t have to involve any suspicion of criminal behavior.1New York State Unified Court System. People v De Bour The bar is genuinely low. Someone walking near a closed business after midnight gives an officer enough reason to say hello and ask a question. What the officer cannot do is act on pure whim or idle curiosity. There has to be something specific, even if it is minor and completely innocent.
The officer is limited to brief, non-threatening questions about who you are, where you are going, or why you are in the area. If you are carrying something that looks unusual to a trained officer, they can ask about it. The questions must stay general and non-accusatory. The moment they turn pointed, the encounter has moved beyond Level One and the officer needs a stronger justification to continue.2Legal Information Institute. People v Hollman
You have no obligation to answer, and you are free to walk away. A Level One encounter is voluntary. If you leave, your refusal to cooperate cannot by itself give the officer grounds to escalate. The DeBour court specifically noted that refusing to identify yourself or explain your presence has been rejected as a basis for arrest in New York.1New York State Unified Court System. People v De Bour
Level Two: Common-Law Right of Inquiry
An encounter moves to Level Two when an officer has a “founded suspicion that criminal activity is afoot.”1New York State Unified Court System. People v De Bour This is more than a hunch but less than the reasonable suspicion needed for a full stop. The officer has observed something that, combined with training and experience, suggests a crime might be happening.
At Level Two, the officer can ask more direct, pointed questions aimed at confirming or ruling out that suspicion. The Court of Appeals clarified in People v. Hollman that the line between Levels One and Two turns on the nature of the questioning: once the questions would lead a reasonable person to believe they are suspected of wrongdoing, the encounter has crossed into Level Two. The court singled out a request to search a bag as an example, noting that no matter how polite the phrasing, asking to search someone’s belongings is inherently intimidating and goes beyond a simple information request.2Legal Information Institute. People v Hollman
The critical limitation at this level is that the officer still cannot forcibly detain you. Level Two permits “a somewhat greater intrusion” than Level One, but it must remain “short of a forcible seizure.”1New York State Unified Court System. People v De Bour You are not required to answer, and the officer cannot frisk you or physically prevent you from leaving.
Level Three: Forcible Stop and Frisk
Level Three is where the encounter stops being voluntary. When an officer has reasonable suspicion that you have committed, are committing, or are about to commit a felony or misdemeanor, New York’s Criminal Procedure Law authorizes a forcible stop.3New York State Senate. New York Criminal Procedure Law 140.50 A reasonable person would not feel free to leave, and you are legally detained.
Reasonable suspicion requires more than a gut feeling. The officer must point to specific facts that, combined with rational inferences, would lead a neutral observer to conclude criminal activity was likely. The DeBour court drew this standard from Terry v. Ohio, which rejected stops based on “nothing more substantial than inarticulate hunches.”4Justia U.S. Supreme Court Center. Terry v Ohio, 392 US 1 (1968)
During a Level Three stop, the officer can demand your name, address, and an explanation of your conduct.3New York State Senate. New York Criminal Procedure Law 140.50 New York does not criminalize refusal to identify yourself, but declining to cooperate during a lawful stop can prolong the detention while the officer investigates through other means.
If the officer also reasonably suspects you are armed and dangerous, they can conduct a limited pat-down of your outer clothing. This frisk is authorized solely to check for weapons or objects capable of causing serious physical injury that a law-abiding person would not normally carry in public.3New York State Senate. New York Criminal Procedure Law 140.50 The frisk is not a full search. The officer is feeling for weapons through your clothing, not rummaging through your pockets.
The Plain Feel Limit
During a lawful weapons frisk, an officer sometimes feels an object that clearly is not a weapon but appears to be contraband. In Minnesota v. Dickerson, the Supreme Court held that an officer may seize such contraband, but only if its identity as contraband is “immediately apparent” through plain touch. In Dickerson itself, the officer felt a lump in the suspect’s pocket, ruled out a weapon, and then kept squeezing and manipulating it until he concluded it was crack cocaine. The Court threw out the evidence. Once the officer ruled out a weapon, the justification for the frisk was exhausted, and continued manipulation turned a limited weapons check into an unauthorized search.5Legal Information Institute. Minnesota v Dickerson, 508 US 366 (1993)
Level Four: Arrest
An arrest is the most intrusive action an officer can take. It requires probable cause to believe you committed a crime. Under New York law, an officer can arrest without a warrant for any offense committed in their presence, or for any crime they have reasonable cause to believe you committed, whether or not they witnessed it.6New York State Senate. New York Criminal Procedure Law 140.10
Probable cause sits at the top of the DeBour framework. It demands enough trustworthy information to lead a reasonable person to believe both that a crime occurred and that you are the one who committed it. That is a substantially higher bar than reasonable suspicion, which only requires grounds to investigate.
Once you are placed under arrest, two major consequences follow. Officers can conduct a thorough search of your person and the area within your immediate reach, which the Supreme Court has defined as the space “from within which [you] might gain possession of a weapon or destructible evidence.”7Constitution Annotated. Search Incident to Arrest Doctrine Officers cannot use an arrest as a pretext to search your entire home without a warrant.
If officers want to question you after arrest, they must first give Miranda warnings. Miranda applies to custodial interrogation, meaning you are both in custody and being asked questions designed to produce incriminating answers.8Constitution Annotated. Miranda Requirements Miranda does not attach during a Level Three street stop, which is one reason the DeBour levels matter so much: the rules change with the level.
How Courts Judge Whether the Level Was Justified
Whether a particular encounter was lawful depends on the totality of the circumstances. The DeBour court identified three factors that interact to determine reasonableness: the manner and intensity of the police interference, the seriousness of the suspected crime, and the circumstances surrounding the encounter.1New York State Unified Court System. People v De Bour
No single factor decides a case. Defense attorneys challenge stops by picking those factors apart. Was the neighborhood really high-crime, or is the label applied so broadly it is meaningless? Did the person’s behavior genuinely suggest criminal activity, or was it ordinary conduct that the officer reinterpreted after the fact? The DeBour court was explicit that police “may not justify a stop by a subsequently acquired suspicion resulting from the stop.”1New York State Unified Court System. People v De Bour The justification has to exist before the intrusion, not after.
What Happens When Police Skip a Level
The framework has real teeth because of the exclusionary rule. If an officer acts beyond what their level of justification permits, evidence discovered as a result can be thrown out. In Mapp v. Ohio, the Supreme Court held that “all evidence obtained by searches and seizures in violation of the Constitution is, by that same authority, inadmissible in a state court.”9Justia U.S. Supreme Court Center. Mapp v Ohio, 367 US 643 (1961)
In practice, this plays out through suppression hearings under New York Criminal Procedure Law Article 710. A defendant files a motion asking the court to exclude specific evidence, and the prosecution must show that the police conduct at each stage of the encounter was lawfully justified.10New York State Senate. New York Criminal Procedure Law Article 710 If the officer jumped from Level One questioning straight to a frisk without the intermediate justification of reasonable suspicion, the weapon or contraband found during that frisk becomes inadmissible.
The consequences extend beyond the item itself. Under the fruit of the poisonous tree doctrine, evidence discovered because of an initial constitutional violation is also tainted. An unlawful stop that leads to an unlawful search that reveals a storage locker key, followed by drugs in the locker, can be suppressed all the way down the chain. Cases often collapse entirely once the first link is knocked out.
Rights You Keep at Every Level
Regardless of which level applies, certain rights remain constant. You have the right to remain silent at every level, though invoking that right looks different depending on the situation. At Levels One and Two, you can simply walk away. At Level Three, you are lawfully detained and cannot leave, but you do not have to answer questions beyond what the officer demands under CPL 140.50. At Level Four, Miranda protections attach once questioning begins.
You have the right to refuse consent to a search at any level. Consent is one of the most common ways officers lawfully expand the scope of an encounter, and it is the easiest right to accidentally waive. In New York City, local law requires officers conducting consent searches to explain in plain language that the search is voluntary and will not happen if you say no.11NYC Administrative Code Library. NYC Administrative Code 14-173 – Guidance Regarding Consent Searches Outside the city, no such script is required. If you are unsure whether you are being asked or told, say clearly: “I don’t consent to a search.”
If you believe the encounter has shifted from voluntary to involuntary, asking “Am I free to leave?” forces the officer to clarify your status. If the answer is yes, you can go. If the answer is no, you are being detained, and the officer needs at least reasonable suspicion to justify it. Either way, you have created a record of the encounter’s nature that matters if the stop is later challenged in court.
How DeBour Differs From Federal Terry Analysis
The federal standard for police encounters comes from Terry v. Ohio, which approved stops and frisks based on reasonable suspicion.12Constitution Annotated. Terry Stop and Frisks Doctrine and Practice Under Terry, the analysis is essentially binary: either the officer has reasonable suspicion and can stop and frisk you, or they do not and they cannot. There is no recognized federal framework governing the casual, pre-suspicion encounters that DeBour regulates at Levels One and Two.
That gap matters. In states that follow only the federal floor, an officer can approach, ask increasingly pointed questions, and pressure a person into consenting to a search without needing any particular justification until they physically detain them. DeBour fills that gap by requiring justification even for non-coercive questioning and by drawing a clear line between general information-seeking and accusatory inquiry. New York courts regularly suppress evidence that would be admissible in federal court or in states without an equivalent framework, because the officer lacked the specific level of justification DeBour requires for the type of intrusion they actually conducted.
