Facts
- Jerome Alford stopped on a Washington highway to assist a stranded motorist while driving a vehicle equipped with “wig-wag” headlights resembling a police vehicle.
- Washington State Patrol Officer Joi Haner, suspecting possible police impersonation, pursued and stopped Alford after he drove off as she approached.
- During the stop, Haner observed handcuffs and a police scanner in Alford’s car.
- Sergeant Gerald Devenpeck arrived, discovered Alford was recording the encounter, and arrested him for violating the Washington Privacy Act.
- The state trial court dismissed the Privacy Act charge because recording police during a traffic stop was not a crime under Washington law.
- Alford filed a 42 U.S.C. § 1983 action alleging an unconstitutional arrest; the district court denied qualified immunity, and a jury returned a verdict for the officers.
- The Ninth Circuit reversed, holding the arrest lacked probable cause and rejecting alternative offenses because they were not “closely related” to the offense cited at arrest.
Issues
- Whether the Fourth Amendment requires that the offense establishing probable cause for a warrantless arrest be “closely related” to, and based on the same conduct as, the offense the officer identifies at the time of arrest.
- Whether an arrest is constitutional when probable cause exists for some offense, even though the officer cited a different offense that does not support probable cause.
Decision
- The Supreme Court reversed the Ninth Circuit and remanded.
- The Court held that a warrantless arrest is reasonable under the Fourth Amendment if, given the facts known to the officer, there is probable cause to believe any crime has been or is being committed.
- The Court rejected the Ninth Circuit’s “closely related offense” rule.
- The Court declined to decide whether probable cause existed for impersonation or obstruction, leaving that determination to the lower courts on remand.
Legal Principles
- Probable cause is an objective inquiry; an arresting officer’s subjective intent and stated legal theory are irrelevant, except for the facts the officer knew.
- The Fourth Amendment does not require that the offense supplying probable cause match the offense announced by the officer at the time of arrest.
- An arrest may be constitutional even if the offense cited at arrest is not a crime, so long as the known facts establish probable cause for a different offense.
Conclusion
The Court held that the Fourth Amendment’s probable-cause standard is objective and does not depend on the officer’s on-scene explanation for the arrest; if the facts known to the officer establish probable cause for any offense, the arrest is reasonable, and courts may not impose a “closely related offense” requirement.
