the murders of Drs. David Gunn, John Britton, and Barnett Slepian and the attempted murder of Dr. George Tiller. Tiller was later murdered in his church in 2009. As of 1995, nearly all anti-abortion leaders said that they condemned the use of violence in the movement, describing it as an aberration and saying that no one in their organizations was associated with acts of violence.

An example of such an organization is the Army of God.
