Wow. That's f#@!ed up and unacceptable. Those officers should be disciplined, fired, and possibly arrested. I mean, damn.
Realistically, they're not gonna get arrested, but something should certainly happen to them.
The thing about this that most sticks in my craw is that the law-and-order, she-had-it-coming types are the very same people who scream about how everything the government does is tyranny. Can you say cognitive dissonance?
In fairness, this isn't universal. I know that most people I know personally (myself included) who complain about tyrannical government policies would use this as an example of such policies rather than defending it.
The real problem is cops using force at all. Police should be trained first in foremost in deescalation, and in most countries, they are.
I dunno about 'first and foremost'. Cops do also deal with situations where deescalation isn't possible, after all, and need to be prepared for those as well. Still, they should definitely receive more training in deescalation than they do. The increasing militarization of the US police force is a real problem that's been ongoing for some time now.
