The second volume caused a stir among Armenian students attending UCLA and the Armenian community of Los Angeles at large. Matters came to a head when on the night of 3 October 1977, a bomb, placed by unknown assailants, exploded at the doorstep of Shaw's home at 3:50 a.m., although no one was hurt. A phone call placed several hours later by a man claimed that the Iranian Group of 28 was responsible for the bombing. Turkey's permanent ambassador to the UN disputed this, however, and alleged that Armenians were behind the attack. Shaw made light of the situation and attributed the bombing to the fact that he had probably assigned too many F's. But he claimed that Armenian and Greek students had threatened him over the previous two years and canceled the rest of his classes for the remainder of the quarter. With the controversy unabated ten years later, Shaw would claim Armenians were persecuting him not because of his scholarly views but for anti-Semitism, a charge that was refuted by Jewish organizations, including the UCLA chapter of , on campus, as well as a number of Jewish public figures and scholars.
