Probably a goodly number, but how do they react to the presence of the gestapo wannbes in their ranks? With silence. When every peasant shot and killed is a "good shoot"* how do you separate the thrill killers with a badge vs the honest cops?
*In the last ten years only two incidents resulted in criminal prosecution of police for killing citizens. One was the danziger bridge incident in New Orleans, and two the Kathryn Johnson incident in Atlanta. In neither case were the police prosecuted for murder, but things like violation of oath of office which calrries a much lesser sentence.

I don’t know where you get your “facts”, but it’s not true. I can think of this one off the top of my head because it’s local. They even made a movie about it. You can argue that involuntary manslaughter and two years in county jail was too light, but it debunks your claim. I suspect it’s not the only one.
