Host Renee Montagne talks with Marc Levin, Daphne Pinkerson, and Daniel Voll, the producers of a new documentary on HBO titled Soldiers in the Army of God. The film documents a year in the life of three men involved in the violent fringe of America's anti-abortion movement. The men say the killing of abortion providers is justifiable because it protects the lives of unborn children. Renee's interview comes one day after anti-abortion activist James Kopp was arrested in Europe. Kopp — one of the FBI's most wanted — is suspected of killing Barnett Slepian, a doctor who provided abortions in Buffalo, New York. The documentary airs Sunday night on HBO.
