It's becoming increasingly clear that Jared Lee Loughner is mentally unstable. Sarah Palin's bullseye on Arizona Democratic Rep. Gabrielle Giffords did not direct Loughner to shoot Giffords point-blank in the head on January 8, 2011.
Did the vitriol in political discourse, crosshairs and phrases like "Don't retreat, reload" (by Sarah Palin) or "If they bring a knife to the fight, we bring a gun" (by President Obama) influence Loughner's state of mind?
Perhaps in an idiosyncratic way, according to Dr. Jeffrey Lieberman, chairman of psychiatry at Columbia University. "Political rhetoric provided some of the context for his thinking, the pretext for his actions, but the core reasons for his actions were his psychosis," Lieberman told National Journal.
Regardless of what motivated Loughner to pull the trigger, the tragedy in Tucson has put the tone of political discourse, and those who tend to inflame more than inform, in the spotlight.
