What characterizes a Tier 1 encounter in law enforcement?

A Tier 1 encounter is characterized by a verbal engagement between law enforcement officers and individuals, which is considered consensual. During this type of encounter, the individual is not required to stay or respond and may walk away at any time. The interaction is informal, lacking any coercive elements. Police officers may ask questions, but these interactions do not involve any detention or physical restraint.

In contrast, arrests with probable cause represent a more advanced and serious stage of interaction under the Fourth Amendment, indicating that law enforcement has sufficient evidence to believe a crime has been committed. Seizure of personal property and searches without a warrant also signify scenarios where law enforcement takes action that is regulated by higher standards of suspicion or legal justification, such as reasonable suspicion or probable cause. Individual autonomy and consent are key aspects of a Tier 1 encounter, distinguishing it from these more intrusive actions.
