First, this was a kick-ass opportunity to practice the first reactions of the first responders. No amount of pre-planned exercises can simulate that moment of "What the hell?" that a real event starts off with. Hopefully the LA Times will keep the pressure on in the next few months or so for a study to assess the efficiency of responses.
