Fourth Amendment: Arrests and Detentions Flashcards
General Standards
Include:
- Probable cause
- Reasonable suspicion
- Terry standard
Probable Cause
- (For an arrest)- when a reasonable person would conclude that the individual in Q has committed a crime
- (For a search)- when a reasonable person would conclude that specific items related to criminal activity can be found at a particular location.
PC: Current Knowledge
PC is evaluated in terms of what was known at the moment of the government intrusion (cannot use hindsight).
PC: Obj. v. Subj.
The subjective intent of the officer ordinarily has no place in a PC analysis. The inquiry is focused on what a reasonable person would have done.
Reasonable Suspicion
Belief based upon articulable information used by a reasonable person or cop that the suspect has or is about to engage in criminal activity. Uses a TOC test.
Terry Standard
Reasonable suspicion is required for the stop and frisk.
Arrests: Warrant Requirement?
Generally, no warrant is required for an arrest in public, the police need only possess PC (unless the arrest is inside one’s home). There is also an exception for misdemeanors.
Can Informants Provide PC?
PC may be obtained indirectly through an informant if there is reliability. Reliability is present if the informant’s tip contains specific details. Reliability must be established prior to the moment of arrest.
Stops that Become Arrests
Police observations prior to stop may provide reasonable suspicion that suspect is engaged in criminal activity and justify limited detention and questioning. Any additional facts derived from the stop may then escalate to PC sufficient to justify an arrest.
Arrests in Homes
An arrest warrant is required before police can arrest an individual in his own home, absent exigent circumstances or consent.
Arrests in Third Party Homes
Police generally may not enter one’s home for the purpose of arresting the owner’s guest unless there is consent or exigent circumstances.
Entering a Home Pursuant to an Arrest Warrant (Forced Entry)
Officer only have authorization for forced entry into a home, pursuant to an arrest warrant if they have reason to believe that someone is home.
Exigent Circumstances
Include:
- destruction of evidence
- hot pursuit
Arrest Warrant
Must be issued by a neutral and detached magistrate, supported by PC, and provide the identity of the suspect that is to be arrested. Allow police to arrest the suspect and carries with it implicit authority to search the suspect’s (but not a third party’s) home to execute the arrest if:
- police have reason to believe the suspect is home and
- the suspect refuses to respond to police requests to open the door.
Knock and Announce Requirement
Unless exigent circumstances, exist, the arresting officers must knock and announce their identity before entering to make the arrest. But the violation of this requirement does not trigger the exclusionary rule.
