Every time these is video of police exceeding their ROEs like this, we have protests, and the protests lead in most cases to riots. This carries on for some period of time, a week or so in most places, and then life returns to "normal". You may not like "normal", but I've yet to see any real actions taken to DO anything or CHANGE anything.
The Chiefs of Police will announce some new policies and perhaps install some civilian review board or new training, whatever, and that is that, until it happens again, which it will.
Meet the "new normal", same as the "old normal".
Just with a fig leaf and some flowery prose and blah blah blah.
Let's do something constructive. Or, really, let's appear to have done something constructive which in reality is burfle.
