WICHITA, Kan. (CBS/AP) He had to kill so others could live. That's the argument defense attorneys are set to make Dec. 22 for Scott Roeder, the anti-abortion activist accused of shooting abortion doctor George Tiller.

This is an about face in strategy from their previous statement back in November when Roeder seemingly confessed to the Associated Press that he murdered the prominent and controversial abortion doctor "because of the necessity defense," saying that he was defending "preborn children."

At the time, public defender Steve Osburn said there was no such thing as the necessity defense and that it "does not seem to be the approach that is viable, nor is it the approach we intend to use."

The 51-year-old Roeder, from Kansas City, Mo., is charged with one count of premeditated, first-degree murder in Dr. Tiller's death and two counts of aggravated assault for allegedly threatening two ushers during a May 31 melee in which Tiller was shot in the foyer of his Wichita church.

Previous attempts by other anti-abortion activists to use this defense have failed. The most prominent example was Rachelle Renae Shannon who tried to kill Tiller in 1993. He was wounded but survived and continued to run his abortion clinic. Shannon was sentenced to 10 years for the crime, but remains in jail for other anti-abortion attacks.

Judge Warren Wilbert is set to hear a variety of other motions from both sides according to CBS affiliate KWCH, which is running a live blog of the hearing. The station says Wilbert has already denied a defense motion for change of venue saying that he feels it would be premature to rule out the possibility of finding impartial jurors before attorneys even begin the process.

Judge Warren did say he would keep an open mind and that the court would be closely monitoring all juror questionnaires to spot overriding prejudices.

Prosecutors have said that they would prefer it if abortion were not mentioned at all during the trial, set to begin in January 2010. Instead they want to focus on the details of the May afternoon when Roeder allegedly terrorized Dr. Tiller's Wichita church.

Judge Wilbert's ruling on whether to allow the necessity defense could potentially set the eventual course for a verdict when combined with Roeder's media confession and a significant amount of evidence against him.
