I once caught dashcam footage of a hit and run. Clearly see the license plate, the vehicle occupant - easy case closed stuff. Called the local non-emergency number for the police station and they wouldn't even give me a place to send the footage, much less do anything about the fleeing driver. Had I been smarter, I would have given it to the insurance company of the car that had been hit - but lesson learned for next time.

Footage does nothing to deter people and it has no consequences. It can only be used against the interest of common people - because stopping crime does not lead to meaningful profit. Selling security devices to folks, charging per the hour for security checkpoints, selling x-ray machines, well, that's very profitable - but you can't do those things when nobody is concerned. Harvesting data, selling facial profiles - again, profitable, extremely so.
