In the wake of the July 2005 London bombings, the British government created the Prevent programme as part of its counter-terrorism strategy. Prevent says it seeks to put an end to stop terrorism and support for terrorism in the UK by engaging the Muslim community. Recently, Prevent has started offering mandatory training to civil servants on how to identify potential terrorists and report them to the authorities. However, many in the Muslim community feel they are being unfairly targeted by Prevent, which they say is a surveillance programme. Al Jazeera's Matthew Cassel looks at the effect Prevent is having in Muslim communities in Birmingham and Manchester.
