Murder of David Gunn
The murder was one of reasons why   in 1994 of the federal Freedom of Access to Clinic Entrances Act was passed. From March 1993 through May 2009, Gunn was the first of a total of four doctors murdered by anti-abortion extremists. Others killed were doctors Barnett Slepian, John Britton and George Tiller. Gunn's murder helped lead to the passage of the Freedom of Access to Clinic Entrances Act. Gunn's murder also prompted Paul Jennings Hill to issue the Defensive Action Statement, signed by 30 anti-abortion leaders, which stated their belief that the killing of doctors who perform abortions was justified. Hill went on to murder physician John Britton and Britton's bodyguard in 1994.
