So what body language was James Blake showing when he was tackled by police, or Amadou Diallo when he was shot 41 times by plainclothes cops. It's amazing to me the lengths people will go to justify racism.
I'm completely unfamiliar with both of those names but based on the way you phrased it I'm happy to accept your implication that police officers involved behaved inappropriately and probably illegally. I don't see what that has to do with what I said. If you're a white dude wearing a biker gang jacket and generally acting the fool I expect you to be harassed the same way I expect a black person wearing gang colors and reeking of pot to be harassed. This isn't rocket science.
