Correction: Her daughter was injured. But not killed.
In school settings where mass shootings have occurred, where a firearm was used against the killer, the killer only averaged 2 victims. Where firearms were forbidden and the police were called, the average body count was 14. When an armed citizen confronted the shooter with deadly force, the shooter either surrendered or killed himself. Scapegoating the firearms and their owners, people who are not and will never be a threat, is just EVIL.
