No. How do you know how many good cops didn't report bad cops?
Because of all the bad cops caught on video.
That's just what is caught on video...it's hardly the breadth and scale of the abuse and corruption.
This shit has been going on forever, we're only seeing it now because everyone has cameras on their phones and can record...that is, if the police even let you record them...which many of them don't, despite you having the Constitutional right to do so.
