Somehow I'm not surprised. Incidents are now caught on camera and spread around the news & social media. Yet, in a large portion of the cases where the cops are clearly in the wrong they get a slap on the wrist if that. There is no real incentive to change their behavior camera or not.
It isn't a thin blue line. It's a big fat highlighter blue bar. The people, vs the Judicial System. And they're the ones that make and enforce the rules.
