I don't think his killing was as much to do with race as it is to do with incompetent (just plain thick) policemen.
They've done exactly the same thing to people of other races too in the past and it received way less headlines than it should have done in my opinion, the case of Tony Timpa is disgraceful -

The officers joke and laugh that the guy they're kneeling on has fallen asleep and when the medics arrive and they realise he's out cold the following exchange takes place
Cop that was kneeling on him - "Oh **** I hope we didn't kill him"
Other cop - "What's this "we" talk about?"
All cops - "hahahaha"
A few moments later once the guy is in the ambulance and the medics are getting breathing apparatus together one of the cops approaches saying "I've got his mother on the phone" before he's abruptly interupted by a clearly pissed off medic saying "He's dead."
George Floyd was a catalyst for it all kicking off, the straw that broke the camels back, whether he was a nice person, a criminal, black, white, asian, on drugs it doesn't really matter, nobody should be treated the way he was and nobody should be killed like that, the officers need to be held accountable and the standards of policing needs to improve immensely imo as a lot of them aren't fit for purpose, yet carry around lethal weapons and usually have a badge to hide behind when they **** up.
