On September 9, 1980, a group of anti-war activists known as the Plowshares Eight were arrested for breaking into the Re-Entry Division of the GE Space Technology Center, damaging several nose cones designed for the Mark 12A nuclear warheads. They also poured blood on several documents and offered prayers for peace. The group included Daniel Berrigan, a Jesuit priest, author and poet from New York City, and his brother Philip Berrigan, father and co-founder of Jonah House in Baltimore, MD.
They went to trial in Norristown, PA in February of 1981, charged with over ten different felony and misdemeanor counts. During the trial, four were re-arrested for again entering the GE site. After a lengthy court battle, the case was finally settled ten years later. A motion picture entitled In the King of Prussia, starring Martin Sheen and many of the actual members of Plowshares Eight was released in 1983, depicting many of the actual events.
