At a minimum, watch 100 videos. I did last night, only took about an hour, it's easy to find some to nitpick, some which are ambiguous ... and plenty that are totally horrifying.
If you can watch 100 videos in a row from Greg Doucette's list and say, "the militarization and use of force tactics of US law enforcement are not a problem" then I'd like to hear why you think so given this evidence.
Otherwise you're not speaking from an honest grappling with what these videos contain.
There are way too many cases where a cop provokes a confrontation, often by stopping to allow someone else nearby to run into them, and every other cop in the group responds by beating anyone nearby and shoving back anyone with a camera.
You don’t get coordinated responses like that without planning and practice.
This is absolutely true, but the problem goes much deeper than just the police force itself. We seem to want to solve every imaginable social problem with police/courts/prisons. Drug abuse needs to be viewed as a public health problem, not a criminal problem. Homelessness as a housing and mental health problem, not a criminal one. Many other issues as economic problems not criminal ones. Address the root cause, rather than sending people with badges and guns. I realize this is easier said than done, but it's clear the old approach is no longer acceptable to society.
"Address the root cause", exactly, and the root cause is the unjust laws. Though cops pretty much never being found guilty for unjust use of violence is a big one too, and I wonder what law changes can solve that issue.
So we have a continual cycle of crime-punishment that doesn't mitigate enough, simply because the underlying problems remain, until our country stops with the "you're on your own" mentality and starts supporting social programs better.
