Why do civilian lawmakers even need to pass laws for this?
The police should be reporting their technologies, their techniques, and their standard operating processes to a civilian oversight board.
Otherwise, the police are operating above the law.
Well, we already know that they do. But still, the police department must fall under legal civilian control.
Otherwise, you will end up with a militarized police system, that is accountable to no one but themselves. They end up becoming the foxes that guards the henhouse.
