Anyone who blows off the armed personnel idea really interested in saving lives. I would love to see this, all the nay sayers participate in the simulations that many companies offer to police and military with laser and airlift type of weapons. Let them be the active shooter in the simulation and set up a similar environment to this last shooting and Sandy Hook. Run it 5 times with no armed personnel, and 5 times with a guard with an AR15 hidden near all enter points. Then add a couple teachers, not forced but voluntarily would want to have a weapon in a fingerprint lock box in a desk. If the results don't show a huge increase in lives saved, not to mention the deterrent factor i will sell my AR and join the left side who thinks arming properly is not going to work.
