A judge in Wichita ruled that Kansas law did not allow a so-called “necessity defense” in the trial of a man charged with killing a doctor who performed abortions. The man, Scott Roeder, 51, has confessed to shooting Dr. George Tiller on May 31 and said it was necessary to save “unborn children.” In his ruling, Judge Warren Wilbert cited a 1993 criminal trespassing case involving an abortion clinic in which the Kansas Supreme Court said that allowing a person’s personal beliefs to justify criminal activity to stop a law-abiding citizen from exercising his rights would “not only lead to chaos but would be tantamount to sanctioning anarchy.”
