On Sunday, President Obama declared Wednesday's horrific assault at the Inland Regional Center that took the lives of 14 people and left another 21 wounded an act of terrorism; it was near impossible to imagine any other characterization. The initial theory that the shooting might be explained as a disgruntled employee taking out his anger on coworkers seems increasingly unlikely. Yes, Sayed Farook, one of two alleged shooters in the incident, was a county health worker and the scene of his crime was a staff holiday party hosted by his employer at which Farook was in brief attendance. But, when he stalked out of the gathering early, Farook did not just go pull a pistol out of his car and walk back inside to impulsively act out his anger. He returned with his wife, both dressed in combat gear, and they were armed with assault rifles, pipe bombs, handguns and hundreds of rounds of ammunition.
