The anti-abortion activist accused of killing Dr. George Tiller has warned that more violent acts are planned against abortion providers. In a phone interview from jail, Scott Roeder told the Associated Press, “I know there are many other similar events planned around the country as long as abortion remains legal.” Roeder called the AP on Sunday, one day after 1,000 people gathered in Wichita, Kansas, for the funeral of Doctor Tiller. On Friday, the Justice Department announced it had launched a federal investigation into Tiller’s death.
