The genetic difference between any two "races" in the human race is laughably small - on the order of classifying people by nose or ear size.

Color is just an easy thing to do, I guess.

Anyway, murderers are bad, but could someone explain why its special that they are illegals? To my knowledge, not all illegals murder (the stats seem to show them coming in just below blacks as far as% of lawbreakers goes) but its somehow special that they are illegals?
