How in the world could a gun in a teachers locker in the teachers lounge help prevent a school shooting?
It's not. It will, however, significantly shorten the amount of time it takes an armed person to confront the shooter, and thus decrease the number of people the shooter is likely to kill. Which in turn saves lives. Isn't that our objective here? I get that some of you seem to want to wait for this perfect theoretical solution where we magically make the world free from any possibility of a person with a gun showing up on a school campus and shooting our children, but until that happens, isn't reducing the statistical number of fatalities from such shootings a worthwhile thing to do?
Is the gunman now gong to wait patiently while the teacher runs to the lounge and grabs his piece??
Does the gunman wait patiently until the police show up? No? So if we assume it takes less time for a teacher to run to their locker and retrieve their gun than it'll take for the police to arrive, then this is better than waiting for the police to arrive, right? I mean, barring that aforementioned mythical magical solution that ends all school shootings, our options are "wait for the police to show up and stop the shooter" or "try to stop the shooter before the police get here". Why not give our faculty members the best chance at doing the latter and perhaps saving some of their students in the process?
Are we really so afraid of guns that we'll ignore this possibility?
