You said: "You've got to wonder where the hate for the cops was when they were gunning down black folks left and right a few years back with near complete impunity."
One incident would not be "gunning black folks down left and right a few years back..." There is no evidence of racism in this case. You completed that sentence with "...with near complete impunity." This officer was quickly arrested and charged. He was also quickly fired from his job as a policemen. He was tried in court under state and federal charges, convicted and sentenced to 20 years in prison. That is not impunity. And this was an unusual case where the officer was guilty of using unreasonable force.
I'm curious why you picked this lesser known case. It does not support your earlier statement but that picture does suggest it. You know that what I said is true: "There was not even one case of a racist policeman shooting any of those black crime suspects resisting arrest. Not one. Read the conclusion of the local, state and federal investigations, and grand jury reports."
This case is probably the best choice for you, though, because of the picture and the fact the policeman was wrong. But no racism, no pattern of racist cops and the officer was held accountable.
Also, before that picture, the suspect had assaulted the policeman, had been tased and had taser wires attached to him. The suspect physically put both the officer and himself on the ground in a struggle and had knocked the taser from his hand and to the ground before fleeing.
Still, the officer was convicted because the suspect was no longer attacking him when shot.
The point I made still stands. Most people were deceived into believing police were shooting black suspects because of their race, which was not true, and in the other highly publicized shooting cases the officers acted appropriately.
