I have a buddy that is correctional officer and has been doing that job for 21 years. He has told me many times that the American public would be shocked at how many black prisoners are converting to Islam while locked up. According to him it is epidemic. From what he tells me and what you can find online, the blacks initially do it to get special "religious" rights while locked up. Special foods, special prayer times, special recreation and so on. Purely selfish but not surprising. However, the real issue comes into play because many Federal, State prisons actually allow Imams in to "teach", which often takes the form of radical Islam.
