Of all the rampage shootings in the last decade, how many ere in a gun-free zone, defined as either a gun-free zone mandated by law or one mandated by policy (such as malls that forbid weapons)?
Then, if any took place outside of a gun-free zone, how did those each end? Casualty rates, did the shooter leave the scene? Who stopped the shooter?
See, the gun-grabbers ignore the whole gun-free zone/defenseless victim thing just as they lump gang shootings in with rampage shootings because they're dishonest and will say and do anything to disarm the plebs so their dreams of a totalitarian dystopia might come to fruition.
