Correct me if im wrong but the issue with the prisons were not that Imams (the official state accepted ones) promoted extremists but rather from the convicts some acted as Imams and spread radicalisation between convicts. There was an UK documentary about it, a guy that did it and got transfered prison after prison because he promoted hate and extremists while being a religios leader and an inmante at the prison. And the other inames believed in him so when they got out they joined him.
Found the Documentarie, it's called "From Jail to Jihad"
If anything I would give funds to have prisons with 1 cell 1 convict and have as little social interaction as possible between themself. That's kinda the only way to make sure they won't convert and radicalize.The Muslim prison population in England and Wales has doubled in the past ten years to nearly one in seven inmates. This rise is five times faster than the increase in the overall jail population.
Evidence shows most Muslims are not radicalised, but the prison system is also home to the UK's greatest concentration of Islamic terrorists and extremists. Many more are converted or radicalised behind bars.
Reporter Raphael Rowe follows one radical convert as he leaves prison, interviews some convicted terrorists and extremists about their experiences inside and asks if the authorities are doing enough to prevent the increasing threat of radical Islam inside prison.
