In most instances where an armed citizen uses a gun to stop a would be mass killing, all he had to do was display his gun to the attacker. The Left is incapable of acknowledging the mere presence of a lawfully owned gun as a valid deterrent.
I've been looking for stats on this, on the fact that in most cases the sole display of a weapon by a lawful citizen stops an hell-bent killer. But I have a hard time finding them stats. It would help when debating lefties.
See, that’s the problem: it works.
Display gun, attacker gives up, nobody dead, nothing worth reporting, no statistics.
The Left’s axioms require deaths to justify their goals.
