Better security is the best answer
Recently, on one of Neil Cavuto’s shows, a security executive explained how the “man trap” works. It would not matter whether a staffer were in the school or not. Video cameras and sensors would determine an unauthorized intruder and would be able to hear a gun shot (not a car backfire or other similar noise but a gun shot).
Lockdown would be instituted by supervisors in a remote location and a 911 call initiated. Classroom doors and entrance doors to hallways would be closed and locked by magnets. The prospective shooter would be isolated until law enforcement could arrive.
This is a great system and would work better, in my opinion, than arming school administrators. None of the executive orders I have seen would prevent a shooter from going into a school and go on a shooting spree. It makes little difference if the magazine holds 10 or 30 rounds — lives would still be lost. Better security is the best answer. The only guaranteed outcome of the president’s executive orders is that law-abiding people would be the only ones affected!
