How old are you? and of course, what color is your skin?
I could have written EXACTLY what you did in that original post when I was a teenager. Used to happen to me a lot, and I was very straight edge and law abiding.
Spent a lot of time face down on concrete handcuffed for looking 'nervous', but still never gotten a ticket or been arrested in my life.
Hasnt happened to me a single time since i turned 20.
