I feel like this should be obvious by now, but "gun-free zones" endanger lives. If the goal is really to protect innocent people from criminals, we should eliminate "gun-free zones".
Every public mass shooting since 1950, except for two, has occurred in a gun-free zone. This shooting is no different.
The Umpqua Community College is a gun-free zone, as are the locations of many recent shootings: the Lafayette, La., theater; the Charleston, S.C., church; the military recruiting center in Tennessee.
Guns were outlawed at all these locations, and yet the killers ignored the bans. Plus, the shooters passed background checks -- as did the Oregon shooter, who passed several background checks in purchasing his firearms.
