Earl Leslie Krugel (November 24, 1942 – November 4, 2005) was the coordinator of the Jewish Defense League in the Western United States. In 2005, he was sentenced to prison on charges of terrorism after he confessed to plotting, with the group's leader Irv Rubin, to blow up the office of Arab-American congressman Darrell Issa and the King Fahd mosque in Culver City, California. He was kept in protective custody for three years for the 2001 bomb plot. He was transferred to a medium security federal prison following his sentencing where he was then murdered three days later by a fellow inmate, who struck him in the head with a block of concrete.
