Oklahoma judge rules Flock ALPR searches violate Fourth Amendment

Federal Judge Sara Hill ruled on October 1 that police improperly used Flock license plate recognition data to track Melisa Kyle without a warrant. The decision, citing the June Chatrie geofencing ruling, is the first to find that historical ALPR searches can violate the Fourth Amendment.

• Judge Hill called the Flock search an "unconstitutional warrantless search"
• The officer found 50 instances of Kyle's car traveling over a month
• The ruling relies on the June Supreme Court decision in Chatrie
• Evidence from the subsequent vehicle search was ruled inadmissible
