In support of your argument: Obama has said in his 'fatherhood speech': "We know the statistics - that children who grow up without a father are five times more likely to live in poverty and commit crime; nine times more likely to drop out of schools and 20 times more likely to end up in prison. They are more likely to have behavioral problems, or run away from home or become teenage parents themselves."

Almost 65% of black children are raised without a father (white: 24%). Together these numbers imho give a much better explanation towards black crime and disadvantages than inherent bias.
