Earlier this week my dog was going nuts in the kitchen. I couldn't figure out why. Finally, I realized that I could hear male voices. Couldn't figure out where they were coming from. Dog continued to be agitated about it, so finally I went outside to get an answer. There were three black teenaged boys leaning against the side of the building by the basement door, talking and sharing a bag of chips. When they saw me, the first thing they said was "we're not smoking anything" and then when I started talking to them and explained that they were on private property and driving the dog nuts so they had to go, they said "thank you for not calling the cops".
They couldn't have been more than about 14 or so. But they knew that eating chips somewhere they didn't belong could result in the police (or an irate neighbor with a gun).
Compare that to a while back, literally the day after the Newtown, CT school shooting. A group of white teenaged boys -- right about the same age, now that I think about it -- were playing with air rifles up and down the street, hiding at the corners of buildings and behind bushes, etc. I ran out and told them they had to stop immediately because all the adults were on edge and they might get shot for real as a result....but just the fact that these boys had no sense that their actions might result in the police being called was a real snapshot of white privilege.
Same block (on the south side of Chicago), same ages, very different actions....and the likely consequences of those actions would be determined more by the color of their skin than by what they were actually doing.
