Mass killers have . . . explicitly talked about their desire to attack gun-free zones. The Charleston, S.C., church shooting in June was instead almost a college shooting. But that killer changed his plans after realizing that the College of Charleston had armed guards.
The diary of the . . . movie-theater killer, James Holmes, was finally released just a few months ago. Holmes decided not to attack an airport because of what he described in his diary as its “substantial security.” Out of seven theaters showing the Batman movie premiere within 20 minutes of the suspect’s apartment, only one theater banned permitted concealed handguns. That’s the one he attacked.
Or take two cases from last year. Elliot Rodger, who fatally shot three people in Santa Barbara, Calif., explained his reasoning in his 141-page “manifesto.” He ruled out various targets because he worried that someone with a gun would stop his killing spree. Justin Bourque shot to death three people in Canada. On Facebook, Bourque posted a picture of a defenseless victim explaining to killers that guns are prohibited.
