A recent Supreme Court ruling in Chatrie v. United States found that geofence searches of cell phone location history require a warrant, and legal scholars say the logic could extend to automated license plate readers (ALPRs). The decision may force major changes in police use of ALPR networks, which can reveal travel patterns, home addresses, and visits to sensitive locations when combined with other databases. #Chatrie #FlockSafety #ALPR
