Declaring schools to be “gun-free zones” makes them especially good places to commit mass murder—this is more NRA propaganda that happens to be true. With the exception of the attack on U.S. Rep. Gabrielle Giffords in Tucson in 2011, every mass shooting since 1950 has taken place where civilians are forbidden to carry firearms.
