considering the size of the campus, normal noise levels, communication, etc.
um, gun fire (unless you are using a silencer and I haven’t heard the nut was) is very, VERY LOUD. It would easily rise above normal noise level. I realize kids are loud, but kids being kids is not the same sound as gunfire and screaming.
No, but it does prevent you from hearing reports over the walkie-talkie WHERE the echoing gunfire is actually coming from.
I am talking about having enough police so that at least one would heard the gunfire with his own two ears, not through a walkie-talkie. Even with echos, I don’t think it would take too long for trained police officers that are sufficiently spread throughout the school(in sufficient numbers for the size school) to find where the repeated gunfire and screams are coming from.
AFAIK there was one guard. Tracking the source of gunfire in a semi-enclosed concrete echo chamber is a tough enough problem that we build and distribute these to law enforcement. You can’t necessarily follow the screams because people who have fled the scene continue to scream, people at the scene may in fact be to afraid to scream. It’s really not as easy as you think. A walkie-talkie confirmed location and status would be very helpful to any responder.
