Arizona's remarkably progressive involuntary treatment laws might have allowed Loughner's school to act. They permit involuntary evaluation and treatment of a person who desperately needs it.

Jared Lee Loughner was a sick, tortured soul, and trying to find deep meaning in his favorite books list is a fool's errand.

It is outrageous how quickly so many jumped at the opportunity to politicize this tragic shooting, blaming the tea party and conservative political rhetoric without a shred of evidence to back those claims.
