He got fired and arrested etc. and it does seem to be more of a baffling and idiotic mistake than anything else, based on his prior history ... but still, there's some disconnect in the teaching process for American cops if this guy's reflex action is to try to put four bullets in a very unlikely potential threat.
EDIT: and the victim is fine, he only got hit once and recovered.
It's pretty clear that white cops in the south are wired to see threats less rationally when they're dealing with a black guy. I think at this point it's basically a biological thing, subconscious in most of them (some are just overt racists, but not all).
Let me rephrase anti-cop into cop anti-. Anything where the police are the antagonists is jumped on. This does not excuse them being the antagonists, but that happens all the time and it's not clear to me why people share stuff like this over a long historical read on Iran, or a new Nature study. It smacks of groupthink, or maybe just laziness. At some point it's just voyeurism if we're all vividly aware that many police departments in this country have huge issues and keep watching the videos and shaking our fists and nothing concrete happens. So I don't usually post this kind of thing. I actually shared this video for a specific reason: it shows that "good" cops can definitely still be affected by the subconscious racism I mention in my above post. This is a decorated veteran of a lot of police work, who doesn't have any sort of history of racism like so many of the perpetrators of these acts, and who still panics when a black guy reaches into a car. That's an important lesson.
