A Kansas judge will begin hearing motions today about whether or not to allow the killer of an abortion doctor to present a "neccesity defense," claiming that it was necessary to kill the physician to save fetuses. Scott Roeder, 51, has admitting gunning down Dr. George Tiller last spring at the doctor's Wichita church. The prosecution has filed a motion to block Roeder's planned defense. He's scheduled to go on trial next month.
