Nothing short of concealed carry will solve the problem of mass shootings. Anyone can run through a metal detector and past the unarmed rent a cops and shoot up a place full of sitting ducks.
Exactly right. As long as would be killer has Knows where people to find unarmed people they will have a free fire zone whenever they want one.
As of today a free fire zone can be found at any local High School.
In some schools you may have to shoot a cop or two but that shouldn’t present too much of a problem with a little planning and superior fire power.
Only when the perp has no idea where or when the shot may come is there true deterrence.
