Seven Catholic Plowshares activists were arrested early this morning while staging a protest inside the Naval Submarine Base Kings Bay in Georgia—the largest nuclear submarine base in the world. The activists entered the base on Wednesday night on the 50th anniversary of Martin Luther King’s assassination. They were armed with just hammers, crime tape and baby bottles containing their own blood. The activists said they were following the prophet Isaiah’s command to “beat swords into plowshares.” They hung banners inside the base reading “Nuclear weapons: illegal–immoral.” They were also carrying a statement that quoted Martin Luther King describing the United States as “the greatest purveyor of violence in the world.” Among those arrested were the Catholic priest Steve Kelly; Martha Hennessy, the granddaughter of Dorothy Day; Carmen Trotta of New York Catholic Worker; Clare Grady of Ithaca Catholic Worker; and Elizabeth McAlister, who co-founded Jonah House in Baltimore with her late husband Phil Berrigan.
