Undercover

the long version

"Undercover lifts the lid on police surveillance, and a programme to covertly monitor political activists that has been one of the government's best-kept secrets since 1968. It exposes the world of wire taps, private investigators, surveillance units, vehicle tracking devices, and secret government databases that list forensic details about all citizens who take part in peaceful protests. It tells the gripping human stories of six police spies, part of a covert team of agents that for four decades have had license to break the law and sleep with the enemy. Chief among them is PC Mark Kennedy, whose audacious seven years living a double-life as an environmental activist were made public in January 2011, in the worst scandal concerning undercover policing in British history.
