I was perhaps a little to confrontational in this one, I am sorry about that. The link has given me some rather interesting studies I will be looking into a tad more, although I would like to point out that certain american circumstances could play into that a good bit, such as the ghettos being primarily black populated, at least to my knowledge, thus skewing some of the statistics, but I won't say that this is the only reason, more a tad of a word of caution. Thanks a lot for this well put together reply. I suppose without getting upset here I wouldn't have managed to get this kind of insight so uh...I suppose job accomplished?
