Black or not, what is so difficult about complying with a peace officer's commands, EVEN IF you are in the wrong? The street is not the proper venue to argue your case. Shut up, comply, and then sort it out in court if need be.
Not a one of these guys I've seen get blasted has done anything to help their situation. Clearly, fighting it out in the street with the racist police officer is the proper way to go about it.
Yea, I'm white. So no I can't say that I know how you feel. I'm sure it sucks, and at times I do feel for those that aren't. But racism, unfortunately, still exists (on both sides). Suck it up, deal with it, and make the best that you can of it. You can't cure everybody of it.
