You guys are fucking morons, rambling on about lower IQs in black people in some feeble attempt to 'scientifically' justify your ignorant and unsophisticated world views. Jesus tapdancing Christ, it's 2008. Read a book.
The amount of genetic separation that sets apart black people from white people (or any race from any other race) is so absurdly minuscule that it's not even worth a discussion, let alone an attempt to explain why one group's IQ is lower than another.
What's at work here is completely left to social factors, which is a whole other discussion that I won't even bother to get into.
And when it comes to the OP's topic, rest assured that this guy will be dead within a few months of his sentence. As soon as the other prisoners find out the details about what he did, he's done. Prison justice never fails.
