Finally, a "gun free zone" actually worked

Tragedy in Ohio

Somalian Muslim Abdul Razak Ali Artan, obviously aware of his school's gun-free policy, used his car and a knife to attack nine people on his OSU campus.

Mr. Artan's obedience to those rules didn't prevent the Left from immediately citing his attack as another example of the need for stricter gun control laws, but what are you going to do with these people?
