In Germany bodycams do exists, but it is rather decided by each state if they are used and where. Also some states are still testing. I hope it gets to be a requirement for the police here.

those recorded also have absolutely no rights so a mother crying because her baby was found dead cannot request a right to privacy/removal.

Oh god, also no way to censor the face or voice of the mother? Its humiliating. No need for the public to see this...

it should be noted that americans are this quick to record everything because it played a huge part in minorities being able to document what was done to them.

Absolutely important. I personally have a fear, that they manage to tamper it somehow. I need to inform myself how this all works I guess.
