Guns Not Guard

An armed guard or guards at the entrance to a gathering place might not prevent a massacre. If a potential assailant knows the location of armed security, he may attack them first, by surprise, and end up having more guns and ammunition with which to commit a massacre. Attacks will only be deterred by preserving the element of doubt in the mind of an attacker. If one or several security personnel are dispersed within a crowd with concealed firearms, a potential shooter will never know who will be able to resist him with equal force. This is the only common sense measure that has a chance to work in curtailing mass shootings.
