During the 1980s, more than 75 right-wing extremists were prosecuted in the United States for acts of terrorism, although they carried out only six attacks during the decade. In 1983, Gordon Kahl, a Posse Comitatus activist, killed two federal marshals and was later killed by police. Also that year, the white nationalist revolutionary group The Order (also known as the Brüder Schweigen or Silent Brotherhood) robbed several banks and armored cars, as well as a sex shop; bombed a theater and a synagogue; and murdered radio talk show host Alan Berg.
