And that camera evidence in the future would change that. Now, I'm not so sure. I feel there is a lot of non-refutable behaviour caught on camera which is never prosecuted and just brushed over.
Pervasive video recording means we get to see more of the day-to-day atrocities being committed but that doesn't matter much in most cases because the people in power already knew and don't care.
We (obviously) need to do more downstream in the funnel. As great as lines are about voting carefully, that doesn't really seem to fix the problem. Maybe pooling money and naming and shaming the people who don't chase these cases? Of course, that also risks the angry mob problem.
But the only technology that can really fix this is training. And changing the mentality of law enforcement in the US.
We don't let officers do this where I live.
