There has got to be a better way to effectively police than just pulling over people of a certain race because you are more likely to hit the lottery that way.
Obviously in some instances it is obvious (airport security) but a lot of times people are getting pulled over, gotta sit outside on a 100 degree day while the cops take 15 mins to go through your car, you've got to be somewhere, it's just extremely dehumanizing and if it happened to any of you consistently I really don't think you would like it. Whether it is bad incentives provided to the police or something, it seems worth fixing.
If you're pulling over blacks 60% more than whites and finding contraband 20% less of the time, that's a systemic failure to me. It can be improved upon and that should trickle down to race relations and the police (the "should" may be wishful thinking at this point since the media and some charlatans have really gotten ahold of this issue unfortunately)
You make those numbers up? Police had reason to interact with both sterling and castile. They chose to act monkey.
