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.
That's not my impression when people are openly calling for defunding or disbanding police departments. Those who are concerned with the tails are the sane voices drowning in a sea of insanity these days.
I agree that the outliers are the problem, but how uncommon they are cannot be determined in this way.
