Gun-free zones provide false sense of security.
People don’t stop killers. People with guns do.

Another Mass Murder in Gun Free Zone
....As with nearly all mass murders, this occurred in a gun-free zone. The shooter was breaking the law as soon as he carried a firearm onto school property. He broke the law as soon as he aimed a gun at his first victim, even had he never pulled the trigger.
School-zone mass shootings didn’t begin until after passing Clinton’s Gun Free Schools Act. (There were prior mass murders, but explosives were used to kill 38 children.)
