The Kansas City Star writes about "gun-free" zones:

• Campus officials earlier this year posted the signs — a revolver stamped with a red slash — advertising the University of Kansas ban on carrying concealed firearms.

  George Pisani sees them as invitations to a tragedy.

  “Here’s the myth,” said Pisani, a retired KU biology instructor and gun-safety teacher. “You pass a policy saying you’re gun-free, you put up a sign, shake hands, pick flowers and say, ‘We’re all safer now.’

  “The fact is you’ve just made yourself more vulnerable” to an armed madman.
