A terrorism watchdog in Britain has warned that people of faith could be caught up in proposed legislation aimed at tackling extremism. Speaking during a BBC radio interview, David Anderson QC, the Independent Reviewer of Terrorism Legislation, said the British government’s anti-extremism Bill was “the single document that has alarmed me most” during his time in the post. “I’ve not met anyone who can really define [extremism] in a satisfactory way,” he explained, adding that attempting to tackling such a vague concept will mean “the police are going to feel they have to investigate all sorts of people who are miles away from being terrorists, but may just practise religion in a conservative way.” Pointing out that communism was never banned during the Cold War, he added that to “start applying the force of the law to people who oppose certain values, I think, is a really difficult and dangerous line to go down”.
