Hmmm, that's a tough sell when you look at the footage of some of these cases.
Don't get me wrong, I'm a staunch believer that people should comply with the police. Be polite, follow orders, don't resist. The overwhelming majority of the time this will stop bad things from happening.
But there's a serious accountability and bully mentality problem in the police force. I could find dozens of videos showing the police treating civilians in ways that anybody else would be arrested for. My Twitter feed has a new one pretty much every day.
