Having lived most* of my life as a white person in the USA, I really haven't had much experience with being profiled. However, I live in Germany, where I assume that most criminals are white**. But tonight, riding home, possibly while whistling a carefree tune, I get pulled over by The Man. For a change, I was actually obeying stop lights AND I had lights on my bike -- this is about as traffic-law-abiding as I get. What did I do wrong? I apparently looked like some jackass who was stealing "something" off cars (this was as specific as the cop was willing to be with his suspected perp).
Fortunately, there was a happy ending -- after they checked out my suspicious bag (it held an even more suspicious container filled with salsa), he let me off with no major hassle -- not even a "freedom search".
* I was, however, born a poor black child
** Because, as Sean remarked, "There are a lot of white people here."
