Flock says its cameras make US safer - so why are they being sabotaged? Houston's historic Old Braeswood neighbourhood is affluent and tree-lined. These are not the kind of streets where you would expect to see co-ordinated vandalism. Yet here, four surveillance cameras were attacked and cut down in the middle of the night. The metal poles were severed, leaving the distinctive black oval cameras and accompanying solar panels lying on the ground.

Critics say the cameras, which take pictures of the rear of every car that drives past, are overly broad investigative tools that treat civilians like suspects.

These AI-powered cameras take a picture of the rear of every car that drives past. Footage is retained for a specified amount of time. But little is known about the extent to which Flock is being used - the company does not publish exact data, but
