Police officers in America are taught and encouraged to respond with overwhelming force to the slightest dilemma.
If you're constantly encouraged to swing a hammer everything will look like a nail.
Hence when dude pulled away in the slightest whether to resist or try to drunkenly face the officers the initial response was swift and otherwhelmimgly unwarranted. I'm not justifying it because you can't. But I'm explaining the culture in law enforcement that permits and encourages it. Of course they justify it to themselves by blaming the citizen and dehumanizing him via blaming him for being drunk and "resisting".
I'm untrained. And I could think of a few alternatives to a leg sweep and face plant on a man I outweigh by 100+ pounds. There was no physical threat to the cop. Verbal warning should have been used with a chance to allow the man to comply. But once again most law enforcement "professionals" won't see it that way.
Any challenge to their authority warrants maximum effort. I expect people completely indifferent to the epidemic of police brutality in the US to make excuses to justify or hand wave this away.
Standard? Not for me it wasn't. His feelings for the guy, I dunno, I guess you can take that however you want to.
Huh? Is everything perfect in every situation? No. Sometimes things happen out of our control even when trying to do the right thing all the time. That's what "shit happens" means. Goodness.
Case in point. Except it was perfectly within is control. I know leg sweeping someone like that on pavement can fuck a person up. If a cop doesn't realize this and take appropriate deescalation steps as an alternative they shouldn't be wearing a badge as they're inept.
