Good grief- The first part of that statement was a pretty damm important task.
The second part was unfortunate, but not surprising given the situation. I guess the preference here would have been for the shooting to continue unabated while the "unarmed" security guard cowered with the other students. I guess too, that no LEO should ever respond to an active shooter because of the chance of friendly fire- I will take a Deputy getting shot at and a student wounded to prevent a massacre zone from expanding.
