Constitutional Protections Apply to Government Action
The Fourth, Fifth, and Sixth Amendments only apply to governmental conduct, not private actions, unless a private party is acting as a government agent.
Seizure Defined
A seizure occurs when a reasonable person would not feel free to leave due to physical force or a show of authority by law enforcement.
Terry Stop – Reasonable Suspicion
Police may stop a person if they have reasonable suspicion, based on articulable facts, that the person is involved in criminal activity. A frisk is allowed if the officer reasonably believes the person is armed.
Traffic Stops
Police need reasonable suspicion of a traffic violation to stop a car. During a lawful stop, officers may frisk occupants if they suspect they are armed.
Checkpoints
Police may conduct suspicionless checkpoints if they stop all drivers according to a neutral, articulable standard and the checkpoint serves a special need beyond law enforcement.
Probable Cause for Arrest
Probable cause exists when facts and circumstances would lead a reasonable person to believe that a suspect has committed or is committing a crime.
Warrant Requirements for Arrest
An arrest warrant must be issued by a neutral magistrate, based on probable cause, and must name the suspect and offense. Entry into third-party homes requires a search warrant or exigent circumstances.
Search Incident to Arrest
Police may search the arrestee and the area within their immediate control without a warrant to protect officer safety and preserve evidence.
Cell Phone Searches Incident to Arrest
Police may seize but not search digital contents of a cell phone incident to arrest without a warrant.
Warrantless Arrests in Public
Police may arrest a suspect without a warrant in a public place for a crime committed in their presence or for any felony with probable cause.
Definition of a Search
A search occurs when government conduct violates a person’s reasonable expectation of privacy or involves physical trespass for information gathering.
Warrant Requirements for Search
A valid search warrant must be issued by a neutral magistrate, based on probable cause, and must particularly describe the place to be searched and items to be seized.
Seven Exceptions to the Warrant Requirement
Exceptions include: Exigent circumstances, Search incident to arrest, Consent, Automobile exception, Plain view, Administrative searches, Stop and frisk.
Consent to Search
Consent must be voluntary. Police do not need to inform the person of their right to refuse. Apparent authority suffices.
Plain View Doctrine
Police may seize items in plain view if they are lawfully present, the item’s incriminating character is immediately apparent, and they have lawful access.
Automobile Exception
If police have probable cause, they may search any area of a vehicle that might contain contraband without a warrant.
Inventory Searches
Police may conduct an inventory search of an impounded vehicle or an arrestee’s personal belongings if done pursuant to standardized procedures.
Administrative Searches
Warrantless administrative searches are permitted in heavily regulated industries, for public safety, or pursuant to special needs.
Fifth Amendment – Privilege Against Self-Incrimination
Applies to testimonial, communicative evidence by natural persons. Does not apply to physical evidence such as fingerprints or handwriting.
Miranda Warnings Requirement
Required before custodial interrogation. Custody means a reasonable person would not feel free to leave. Interrogation includes express questioning and its functional equivalent.
Invocation of Right to Remain Silent
Must be affirmatively asserted. Police must stop questioning, but may resume after a significant time and giving fresh warnings.
Invocation of Right to Counsel
Must be clearly asserted. All questioning must cease until counsel is present or the suspect reinitiates. Ambiguous statements are not sufficient.
Miranda – Public Safety Exception
Police may ask questions without giving Miranda warnings if necessary to protect public safety.
Voluntariness of Confessions
A confession must be voluntary under the totality of the circumstances. Coerced confessions are inadmissible for any purpose.
