Bullshit. What was this guy dress like? Black, white, or whatever, you're judged primarily by the way you dress.
A white guy dressed like a hoodrat doesn't fair much better with the police.
Hell, I'm white and I've had a pine pig (our special term for National Seashore park rangers) un-holster his gun because I approached him and asked how much money a parking ticket was going to cost the pretty girl he was writing it for. I was 16 and weighed in at 145lbs, wearing board shorts and a t-shirt.
