Indiana Mall Shooting and the Case Against 'Gun-Free Zones'

A 22-year old was able to stop a targeted attack on an Indiana mall on Sunday, but only because he violated the mall's "no weapons" policy and was carrying a handgun of his own. While the armed citizen isn't likely to face chargers, the defensive gun use is another demonstration that "gun-free zones" don't stop violent criminals, but could prevent law-abiding citizens from acting in self-defense or the defense of others.
