We are well past the point of being capable of recording all police interactions with video. If every police officer was forced to record all activity with body cams (that would be made public through some process) we could scrutinize and hold every interaction accountable by the laws that already exist. That wouldn’t solve everything immediately but I think over time every action would take place as if there was public oversight.
Even during these protests we have instances of people being shot by the police and conflicted recollections from both sides of the events that took place.

Record everything and hold everyone accountable for their own actions.
