I'm going to make an assumtion here- that it was a "gun free zone"

Because the off duty cop that played the terrorist in a Nevada hospital wasn't shot.

...An off-duty cop pretending to be a terrorist stormed into a hospital intensive care unit brandishing a handgun, which he pointed at nurses while herding them down a corridor and into a room.

There, after harrowing moments, he explained that the whole caper was a training exercise.

AND -I think this would take it for the best understatement of the day:

Hospital employees would have been justified in fearing for their lives.
