Protesters blockaded Tiller's clinic during Operation Rescue's "Summer of Mercy" protests during the summer of 1991, and Tiller was shot by Rachelle Shannon at his clinic in 1993. Tiller was wounded in both arms, and Shannon remains in prison for the shooting.
The clinic was bombed in June 1986, and was severely vandalized earlier this month. According to the Associated Press, his lawyer said wires to security cameras and outdoor lights were cut and that the vandals also cut through the roof and plugged the buildings' downspouts. Rain poured through the roof and caused thousands of dollars of damage in the clinic. Tiller reportedly asked the FBI to investigate the incident.
No arrests were made in the 1986 bombing.
