In October 2009, the IRR’s report Spooked: how not to prevent violent extremism first drew attention to concerns over Prevent’s gathering of information on individuals thought to be on a pathway to radicalisation. Now an ongoing research project on counter-radicalisation initiatives in the US and the UK,[1] drawing on information gleaned from Freedom of Information Act requests and interviews with current Prevent practitioners, suggests that the surveillance of significant numbers of Muslims, including children, whose political and religious views are deemed ‘suspect’, is central to Britain’s ‘Prevent’ strategy to counter radicalisation.
