Of course it was political.
In the Fort Hood shootings of November 2009, the right was quick to link Nidal Malik Hasan to terrorism, while the left insisted he was merely deranged. The reactions to the attempted assassination of Rep. Gabrielle Giffords and the murder of six others this weekend offered a mirror image: Many on the left blamed right-wing political extremism, while conservatives insisted that Jared Loughner, the alleged killer, was a lone lunatic, without political motivation.
If a whiff of political opportunism clings to both these sets of reactions, it's because the categories that we use to explain political violence draw bright lines where none really exist. Throughout history, political assassins,even the most clearly unhinged among them,have possessed political motives. That doesn't mean that Tea Party-style rhetoric incited Loughner. But his choice of targets,an officeholder, not a post office or a mall,can't be dismissed as arbitrary. The problem lies in the artificial distinction we routinely draw between political and psychological motives.
