This is a general overview of issues that may arise in police encounters. The information presented is not offered or intended as legal advice.
In general, a police officer may lawfully ask you questions at any time, without having to demonstrate reasonable suspicion or probable cause.
You have a right to refuse to answer police questions, and the right to consult with a lawyer before agreeing to speak to the police. These rights apply whether or not you have been detained or arrested.
The police are not required to inform you of those rights unless they intend to conduct a custodial interrogation (i.e. question you while under arrest or otherwise not free to go).
You are not required to tell the police that you are exercising your right to remain silent.
Police officers may try to pressure or persuade you to speak to them without a consulting a lawyer.
Police officers may say that you are better off without a lawyer.
Police officers may threaten you with a grand jury subpoena.
Police officers may promise leniency in criminal charges or sentencing.
If you are stopped by a police officer, you are legally entitled to walk away unless you have been detained or arrested. If you’re unsure, you can ask if you are free to go.
It is generally a good idea to walk away calmly.
It is generally not a good idea to argue with or insult the officer.
Detention means that you have been stopped by a police officer and are not free to go.
If you are detained, your constitutional rights (including the right to remain silent) apply, but the police are not required to inform you of those rights unless you are arrested.
If you are detained, the officer may conduct a “pat down” (an external check) for weapons.
Legally, a police officer is required to have “reasonable suspicion” that you are armed and dangerous before conducting a pat down.
If you are detained but not arrested, the officer may not lawfully conduct any search beyond a pat-down (e.g. inside your pockets, under your clothing, inside a bag or other item) without your consent or “probable cause”.
You may tell a police officer you do not consent to a search.
Probable cause means that the officer has knowledge of facts sufficient to support a reasonable belief that you are engaged in criminal activity or have evidence of a crime in your possession.
Arrests, like searches, require probable cause.
Police officers will usually tell you if you are being placed under arrest.
Resisting arrest is a crime, even if the arrest itself is unlawful or the police use excessive force in carrying out the arrest.
Once you have been placed under arrest, the police may lawfully conduct a search:
If you are arrested, the police may not lawfully interrogate you without advising you of your right to refuse to answer questions and your right to legal representation.
The police may recite the Miranda warning at the time of arrest or at a later time prior to any interrogation.
You have the right to make a phone call within a reasonable time after being arrested.
The police may not listen to your calls with your lawyer.
But they may (and mostly likely will) listen to any other calls.
You have the right to appear before a judge or magistrate within a reasonable time after being arrested (usually within 48 hours).
The purpose of this appearance is to hear the formal charges against you, decide on bail, and enter a plea.
You have a right to be represented by a lawyer at an arraignment and all other court appearances.
