@Warfire80,
Crime is dominant in poor communities and unfortunately there is more poor black comunities than white, therefore, blacks and other minorities would be more represented in prisons.
I have seen, however, situations where the only explanation I can find is discrimination.
There was a case a while back of a white doctor who went in his office and forgot his child was in the car, the child died. he was given probation as a sentence. Some time passed and a poor hispanic man who was declared mentally retarded went to the track and left his child in the car, the child died. He was sentenced to life in prison. IMO they should've both gone to prison. And I do apologize, I looked and could not find the articles.
