A federal judge decided that Jared Loughner, accused of killing six when he opening fire on a public appearance of Rep. Gabrielle Giffords, D-AZ in Tucson, is not competent to stand trial.

The decision was handed down by Judge Larry Burns, who serves on the U.S. District Court for the Southern District of California.

A pyschologist and a psychiatrist agreed that Loughner is schizophrenic, a conclusion they reached after examining Loughner while he was held at a federal prison in Missouri. The doctors referenced his distrust of lawyers and inability to grasp the justice system.

After the shooting, journalists probing into Loughner's past found what seemed to be warning signals of his mental instability. His former philsophy professor spoke of Loughner's nonsensical, disconnected thinking and said he attempted to get Loughner into counseling, although the professor said he had not detected any violent tendencies. Another professor described Loughner's rant over losing credit for a late paper prompting her to call the police.
