The shelf above Mike Naughton's desk in Bristol University's law school is heaving with files of letters from prisoners who claim they were wrongly convicted and want help.
Naughton's office has become the bustling nerve centre of the University of Bristol's Innocence Project which aims to provide free assistance to the victims of miscarriages of justice languishing in prison.
Students have been giving up their free time to sort through the mountain of correspondence. "They should be out drinking or chasing the opposite sex but they are here getting stuck in," says Naughton. "Their enthusiasm is a inspiration."
