I can certainly buy the angle that the incidents of white cop --> minority violence are probably more exaggerated in the media, and I've personally been attacked (more or less) by a cop that was of my same ethnicity. I was standing in the back of a yard at a party, the cop came over the fence and told me to run to the front of the yard. I could have literally ran 2 steps before hitting a wall of people, and since I wasn't moving fast enough for him, he through me to the ground and put his knee in my back to hold me there while he yelled at other people, then eventually cuffed me...and yes it was hard to breath, yes he was doing it to make a point to everyone else, and yes he was using his power on someone he felt like he could/should be able to control...and no I don't think it was justified and I'm certain this happens every day to a variety of people across the country. There are probably thousands of unpublicized incidences of minority cop -->minority violence and minority cop --->white violence and white cop ---> white violence that don't get reported on, but I do think it affects minorities in a different way than it affects a middle class white kid drinking at a college party.
That is in no way meant to delegitimize the voices in this protest, because I agree with them (the protest, not the rioters). I dated a black girl, off and on, for probably 4 years and I can say first hand that their experience is different than our own. Even the most innocent things that may not have come from a racist place, happen to them and all of that adds up to a type of hegemony that most people in our society just take as normal. Simple things like "you're really pretty, for a black girl" or "you're very intelligent for a black girl" are not coming from a racist place, but are inherently racist. I heard the first one at least a half dozen times, and the second one a couple of times. I also had people yell at us when we were together some place as if an interracial couple was wrong for some reason. There are still some people that believe that in this country, which is mind boggling and further proof of the types of ignorance that minorities have to deal with on the daily. Our "white privilege" to use a fairly current term, is that we don't have to deal with even those simple possibly innocent things that she and/or they deal with on an almost daily basis. Their experience is different, and from being around a 5 foot nothing 110lb girl, I can only imagine the reaction a 6'2" 220lb man would have on people that don't realize they even harbor some of those even subconscious biases. I have friends that are illegal immigrants from Europe (Poland and Romania) and friends that are hispanic and who's families have been here for several generations, and guess which ones have more experiences with racism in their daily lives? To think that some of the people that perpetuate that racism are also LEO's, is not a stretch, it's a reality, and the system that is in place allows them to use their power and authority to do things to people they don't respect or are afraid of.
I do believe all of that has to stop, and over time (generations) things are/will improve in that regard I believe. That sort of thing doesn't go away overnight nor do I think anyone expects it to. What can change more immediately is the process of escalation that LEO's go through. Whether or not violence from a LEO towards minorities is statically at a higher percentage doesn't matter. Even if it's not, it hurts them disproportionately because of their overall experience in our society and in this instance their voice is likely going to be the catalyst for change in a system that has long needed change to happen. LEO's need more training, more accountability, and more transparency. They need better funding, and better access to support resources to deal with some of the emotional trauma that they have to endure on a daily basis. The individual cops aren't the problem, the system that trains them is the problem. In my opinion.
