On February 19, 1999, in Sylacauga, Alabama, 39-year-old computer programmer Billy Jack Gaither was murdered - the victim of a violent hate crime. One of the convicted killers testified he killed Gaither because he was "queer." Why have gays like Gaither and Matthew Shepard become the targets of such brutality? On February 15, nearly one year after the Gaither murder, FRONTLINE correspondent Forrest Sawyer explores the roots of homophobia in America-as a catalyst for hate crimes and as a phenomenon that permeates our society-and asks how these attitudes, beliefs, and fears contribute to the recent rise in violence against gays.
