I was thinking of the VA Tech massacre in which the gunman kept roaming, and firing, and killing inside the building(s) and while police mulled their tactics outside. But the theater shootings apparently were done and over with much faster.
Yes; it did not take long. . .and while all the 'blame/hype' goes to the gun(s) he used; without the 'firepower'; he could as easily have used a 'chemical' attack of some kind; to accomplish agenda. He was wearing a gas mask; and spraying tear gas; but it could as easily been a life-threatening 'spray'.
Point is, the old addage. 'Where there is a WILL; there is a way.' Something the Left; refuses to accept; as it does not fit their agenda. Save for when it is, their 'will' and their 'way'. . .of course.
Meantime; am certain; that Obama is already looking to the 'better' side of this tragedy; inasmuch as it gives him more airtime to arrogantly, expound; w/o having ever, to defend his record or himself. This will take 'air' from Campaign; and the only one left gasping for breath; will be Mitt Romney.
