Here is the thing: It keeps happening. Its not like this is some isolated incident where a cop somehow mistakenly shoots someone. People are shot by police, either out of malice, incompetence or simply not giving a fuck.
Most rarely see any repercussions, and only when there is sufficient public outcry that the case can't swept under a rug.
The thing is, nothing on this will be fixed until it happens to a rich white kid. Until then, most people will go "Good, the thug got we he deserved" if the victim is black/hispanic, or "Too bad, shit happens I guess" if they asian or a poor white person. Nevermind the victim will have to be a saint, any prior dealings with the police will be drug into the light, their character assassinated, all while the police officer is protected.
The narrative isn't controlled by the victim, as it was seen the name of the officer was released at the same as an edited video was put out to turn the discussion away from the officer. Whenever things seem to turn, why suddenly there is a little nugget of info dropped that is generally made up of just the right amount of bullshit to drag the discussion away.
Soon as the video made its rounds and people started seeing holes in it, why now the poor officer suffered this massive head wound. Why he was walking around without difficulty after suffering this grievous wound is not worth mentioning apparently.
