Did you read anything or are you just going to project your own bias on the discussion?
"It's banned in warfare" doesn't make it some egregious WMD. It's banned because all chem weapons are banned per the Geneva convention and adding particular exceptions is a dangerous path to go down. Every single basic trainee in the US Armed Forces is subjected to it and they all turn out just fine (or well, if they don't it's not because of the tear gas exposure). You're using the term as if it's some catch all that ends any and all conversation. Would you like to suggest an alternative to safely controlling dangerous crowds?
> They should disengage
The exact situation I laid out was protestors surrounding an officers vehicle and beating it trying gain access to do him bodily harm. Would you like to suggest how he can disengage? I'd love to hear any ideas you have because driving away is quite literally the safest option there. The alternative is to shoot the people trying to attack him. One most likely results in broken bones where the other most likely results in death. Here's an example in which people swarmed the car that showed up on screen and the officer had to run someone over to escape personal harm. Frankly if protestors surround a vehicle, don't move or clear the way when asked multiple times and given multiple warning, then they 100% deserve to be run over. That's their fault. Don't surround an occupied vehicle in a violent environment and expect nothing to happen.

I didn't say it was "clear cut brutality". I said it probably wasn't okay, but that it's more nuanced than people such as yourself would like to make it appear.
Are you going and holding every single software engineer that writes malware or privacy invading adware responsible? Oh no? Guess that makes you just as bad as them.
Edit: And I should add, nor have you provided evidence to the contrary. How many videos are there of police intentionally ramming into completely peaceful protestors? I'd wager there aren't very many. You're the one claiming that any potentially adverse action taken by a police officer is wrong despite any co-factors or context. Show me a video where the police are running someone over and, with all the context and surrounding information, it still looks absolutely unreasonable.
