What I don't understand is why this guy felt the need to pursue the teenager. If he for some reason thought he was suspicious, he should have left it in the hands of the police. If he believed the police were not going to do anything about it, then tough luck, move on, but don't go confronting the person. It seems to me the Stanford police did not do a thorough investigation at the time of the incident. They just took his word for it that it was self defense, possibly because the victim was black, and didn't bother to do more. This police department has been shrouded in controversy before so this is nothing new and it took this unfortunate incident to bring attention to the corrupt Stanford police.
