Before the recent Virginia Tech massacre, Art De Vany cited a John Lott piece arguing that gun-free zones ensure that victims are unarmed:
Gun free zones may be well intentioned, but good intentions that is not enough. It is an understandable desire to ban guns. After all, if you ban guns from an area, people can’t get shot, right? But time after time when these public shootings occur, they disproportionately take place in gun free zones.It is the law-abiding good citizens who would only use a gun for protection who obey these bans. Violating a gun free zone at a place such as a public university may mean expulsion or firing and arrest, real penalties for law-abiding citizens. But for someone intent on killing others, adding on these penalties for violating a gun free zone means little to someone who, if still alive, faces life in prison.
Unfortunately, instead of gun free zones ensuring safety for victims, ensuring that the victims are unarmed only makes things safer for attackers.
