From jail to jihad

Apparently the Channel 4 Dispatches programme to be broadcast next Monday paints an alarming picture of how preachers in some of Britain's prisons are turning Muslim prisoners into potential jihadists. Strange how it left to Dispatches to make such a programme again, never do the BBC produce a programme that is anything other than positive about Islam. I wonder if the West Midlands Police will be investigating Dispatches after the broadcast of this programme?
