A police officer can ask to speak to you at any time. The duration of the encounter and whether your response is voluntary or mandatory differs depending on the nature of the stop. Generally, there are three types of interactions with the police:
- Consensual voluntary encounter– If a police officer stops you without a warrant, probable cause, or reasonable suspicion that you committed, are committing, or are about to commit a crime and speaks with you, you may refuse to speak with the officer and walk away. In reality, it is often difficult to tell whether the officer is conducting an investigation based on the question he or she asks you; therefore, it is a good idea to be polite and ask the officer, ‘Am I free to go?’ If the officer says ‘yes,’ then you are free to leave.
- Investigative stop– If the police officer has reasonable, articulable suspicion that you have committed, are committing, or are about to commit a crime in violation of any city, county, state, or federal law, the officer may conduct a brief investigatory stop. During this stop, you are not free to leave and the officer may temporarily detain you for as long as reasonably necessary to ascertain your identity and to conduct an investigation and/or dispel his or her suspicion. The officer is required to detain you in the immediate vicinity of the encounter. The officer may also frisk you or pat you down if he or she has a reasonable fear for the officer’s safety or for the safety of others.
- Arrest– In order to put you under arrest, the police officer must believe you have committed a crime. When a police officer significantly deprives you of your freedom of movement or detains you in order to question you about a crime or take you into custody, you are legally considered under arrest. You could be under arrest even though the officer has not used the word “arrest.” In order to be considered under arrest, it must be evident that, under the totality of the circumstances, a reasonable person in your position would feel that you are not free to leave or end the encounter with police. .
If you are arrested, the police officer may search your person and the area within your immediate presence for the purpose of protecting the officer from attack, preventing you from escaping, or discovering the fruits of crime.
