The story of the latest terrorist attack in London is both tragic and extraordinary, starkly contrasting the evil of the assassin and the virtues of his young victims. The red-faced authorities are trying to work out how it came about that a convicted jihadist attending a prisoner rehabilitation conference stabbed to death two of the people who wanted to help him. Meanwhile, and predictably, the event has been politicised. It is being cited as evidence that Islamist terrorists cannot be de-radicalised, and that even if they could, we can never know whether a jihadist who claims to have been de-radicalised is telling the truth. The answer for some? ‘Lock them up and throw away the key.’ Those who believe in second chances, on the other hand, might mention that one of the heroes who confronted and helped to subdue the knife attacker on London Bridge was a convicted murderer on day release. But perhaps before we consider how to punish and rehabilitate Islamists we should think about how to stop young Muslims from being radicalised in the first place. ‘Prevention’ is a catch-all term; for some it is code for cack-handed state interference in the private affairs of religious minorities; for others it is about community-building and a sense of belonging. But is that wishful thinking when communities seem so polarised, even ghettoised? Is it unreasonable of our society to preach “British values” to young Muslims who feel both economically and politically alienated? Or does the blame lie with those on both sides who have fought against integration? Featuring Dr Rakib Ehsan, Dr Usama Hasan, Hadiya Masieh and Dr Rob Faure Walker.
