Flock's surveillance network faces Senate scrutiny over search oversight

A U.S. Senate hearing examined Flock Safety's license plate reader network after the company acknowledged it conducts little oversight of how police search its system and that some cameras can search images for people. The hearing follows September charges against Indiana officers over thousands of unauthorized searches.

• Flock admitted it conducts very little oversight of client searches, leaving agencies to police themselves
• Flock says its cameras can search for people by clothing or glasses, not biometrics or race
• Five Indianapolis officers charged; one made over 4,400 searches involving his wife
• Hackers extracted a camera key decrypting thousands of videos; 1.6M images in 21 days
