Pittsburgh Mass Attack on Jews Not First in U.S.

Although anti-Semitism has been a steady presence throughout American history, until Saturday's mass shooting attack on the congregants of a Pittsburgh synagogue that left 11 dead, the attacks have more often than not been nonphysical. Swastikas and offensive slogans were painted on the walls of synagogues, and bomb threats issued to Jewish community institutions.

If the Ku Klux Klan and other white supremacists carried out an estimated 3,500 lynchings of African-Americans in the century following the Civil War, the number of Jewish victims of the virulently anti-Semitic organization can be counted on a single hand.
