This essay analyzes right-wing activism in Maine’s law enforcement community in relation to the state’s prisoners’ rights movement during the early 1970s. Viewing violent political repression as central to the decline of the radical prisoners’ rights organization, Statewide Correctional Alliance for Reform (SCAR), I argue that vigilante activity and police attacks on prison activists, including Portland Police Officer Edward Foster’s botched attempt to organize a police “death squad” to assassinate local ex-convicts during the summer of 1974, should be understood as the work of a right-wing social movement in 1970s Maine that included activist prison guards, police officers, law enforcement officials, and their supporters.
