Kansas abortion doctor George Tiller was gunned down on Sunday while serving as an usher at his church. Tiller was allegedly killed by an apparent anti-abortion crusader while he served as an usher at his church. The murder has stoked the country's decades-old abortion debate.
Dr. Joseph Booker, the only doctor licensed to perform abortions in Mississippi, says Tiller's death has made him more concerned than usual for his own safety.
