Letting them teach islam in prisons is the first mistake. That invading filth must be banned before there is a chance at reforming anything related to it.
Where have they been? Malcom X’s autobiography decribes this going on in our prisons back then, including his own jail- conversion after brother introdeced him. Started & nutured more of the same. So it’s been known by many for quite a while, but NOW it’s time to start realizing the problem?!?!!
