Lawyers are arguing that one of the drugs the Tucson shooting rampage suspect is being forced to take is making him more dangerous to himself, not less.
The arguments in a filing late Friday add to others that defense attorneys for Jared Lee Loughner have made to a federal appeals court. They're trying to overturn a ruling allowing the medication.
The latest argument says Loughner poses a danger to himself because he is depressed, and one of the drugs he's being given at a federal prison facility in Missouri is making him more rational and thus more depressed.
Loughner has pleaded not guilty to charges stemming from the Jan. 8 shooting that killed six people and 12 others, including U.S. Rep. Gabrielle Giffords.
The appeals court hears the case Tuesday.
