How do you solve a problem like Anjem Choudary, the Islamist hate preacher due for release from prison on Friday? Choudary, whose followers included the killers of Fusilier Lee Rigby and one of the terrorists involved in last year's London Bridge attack, will be tagged and subject to restrictions including a night-time curfew as part of monitoring by the police, probation and security services. But the bigger underlying problem is how to prevent extremists like him radicalising and influencing others during their time behind bars.
This is why the Ministry of Justice is wrong to block academics who want to study why prisoners convert to Islam, including how it can lead to radicalisation. Apparently those behind the decision think that new research wouldn't tell them anything helpful, which serves to highlight a bureaucratic culture more intent on burying its head in the sand than considering fresh approaches.
