Forward Intelligence Teams (FITs) are two or more police officers who are deployed by UK police forces to gather intelligence on the ground and in some circumstances, to disrupt activists and deter anti-social behaviour. They use cameras, camcorders and audio recorders to conduct overt surveillance of the public. An unsuccessful legal challenge has been made against their use of overt surveillance, but in 2009 the Court of Appeal ruled that they must justify retention of photographs on a case-by-case basis. Any retained information is recorded on the Crimint database.
