"The human rights group, Liberty, has just revealed that the Government is operating a secret database of every referral ever made to the anti-radicalisation programme, Prevent."
See: The Government’s Prevent database isn’t about keeping us safe, it’s about control (Metro, link):
“…This database isn’t about keeping us safe. It’s about keeping tabs on and controlling people, particularly minority communities and political activists.
…The majority of information on the database is gathered by public servants who have been co-opted by the Home Office under Prevent and encouraged to view even very young children as potential future criminals.”
