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.
Almost all of them had outright wrong, or heavily misleading titles and/or descriptions with contradictory claims in the comments - and almost none of them provided context to the police actions.
This list is really more about stoking emotions than providing evidence of anything.
I mean look at this one...

A large volume of misleading hyperbolic claims by a biased collector/poster don't get more meaningful through volume of posts.
