I really don't care what color you may be. But by your appearance and or actions you appear to be more of a threat, then I become more aware of what you are doing. I can't be like Jang, who goes through life completely aware at all times. I'm just not that good. I rely on past experinces and popular probabilities.
A black man open carrying in a responsible manner is not going to get any more notice from me than anyone else doing the same. It's when the responsibility level goes down my awareness level goes up.
