Blair Peach was beaten to death by British police in 1979, for protesting against the fascist National Front. The report of Commissioner Cass, kept secret for thirty years, reveals that members of the squad responsible for policing the protest were found with a cache of illegal weapons and a collection of Nazi memorabilia, and concludes:
There is some evidence to suggest that the fatal blow was struck by a member of the first carrier at the scene, U.11., and indeed, an indication that it was the first officer out of that vehicle. This of course, was Officer E. However, there is no evidence of a conclusive nature. [...] ¶ I strongly recommend that proceedings be taken against Officer E, Officer H and Officer F for obstructing police in the execution of their duty, conspiring to do so and attempting or conspiring to pervert the course of justice.
No officer was ever charged. Alan Murray, who admits he was “almost certainly” Officer E, “resigned from the Metropolitan Police, receiving a certificate for exemplary conduct in his career.”
