American terrorist organization responsible for the murder of doctors & nurses (including Dr. George Tiller). They also bomb women's health clinics. Members frequently harass patients at these clinics. These people should be considered armed, dangerous, and possibly psychotic.
When they were outnumbered 3 to 1 by pro-choice defenders at Dr. Carhart's clinic, the Operation Rescue goons ended their protest early and left, taking their bloody fetus signs with them.
