I don't desire for this to turn into a societal debate, but would counter with this:
It doesn't really matter so much the color of your skin as your social standing and community circumstances.
Whether you are white, black, brown, yellow, red, or purple, if you live in a nice home in a well-to-do neighborhood, with no reputation for trouble, and the police roll up because a guy invaded your home and you punched him in the mouth for it, I agree you likely won't be arrested.
But if you're a college kid living in an apartment complex not far off-campus that is a de facto extension of the dorms, you probably are going to be charged. Again, white, black, purple or green.
We make assumptions about each other based on the totality of circumstances. And--for all but a racist minority--skin color isn't even one of the primary elements.
Go Vols!
