This is where the problem lies for solutions. If we are going to look at police interactions we need to determine exactly what we are looking at. An armed robbery suspect will be treated differently than a traffic stop.
So if you just break down the traffic stops for speeding we then have a ton of problems with that data. Race, sex, location, time, speed, traffic, monthly quota time. Then once we try to make those variables the same we get down to individual behavior. I would suggest that females can be the most obnoxious people during a traffic stop because they are just brutal sometimes. Anyway I digress. The problem is we focus on race and not the specific action and then it all falls apart because we can not account for all the variables.
I think if we are going to talk about policing injustices we need to have clear discipline steps for the community and police for misbehavior. I do not see any type of continuity of what the guidelines are going to be. It would be like in my classroom having some rules for interaction behavior but I change it and the discipline applied daily. This happens all the time in education because we leave discipline up to the individuals without specific guidelines.
