Surprisingly, the drill made Beck aware that she would not have recognized the sounds of gunfire. "I would have blown it off as kids' sounds in the hall," she said.
Seriously?! I'd think that two shooters in a room, a large number of shots fired, you'd be thinking, "I wonder if my hearing is damaged."
Our school did a similar drill; a handful of the faculty and about 50 students volunteered to take part during our spring break. The difference - WE staged the active shooting scene (the make-up... there were a couple of places that looked far more realistic than anything I've seen on CSI, Criminal Minds, or any of that sort of show. Police from agencies all over the area entered the school in teams. They knew it was an active shooting drill, but the goal was to make it so realistic as to really freak them out & put them into that frame of thinking. (And, some were visibly startled at several turns; caught many completely off guard.) Great learning experience for the police, and great community service activity for the students to take part.
Major difference: Police cars were double and triple checked for real ammunition and firearms (they were using dummies). Police officers double and triple checked for real ammunition and/or firearms. Then, checked again as they stormed into the building. It was very interesting to watch the whole thing all day. (Team enters, finds the shooter, takes down the shooter, reset, time for the next team.)
(And, I hope if I'm ever pulled over for something, any of the dozens upon dozens of police will recognize me and let me go for being such a good volunteer.)
