Ben Carson, the retired neurosurgeon who is a leading Republican presidential contender, said situations like the July 16 shootings by a lone gunman that killed five military service members in Chattanooga could be prevented by arming officers at recruiting stations.

"I can't think of any good reason why we should disarm them," Carson said Thursday in a phone interview. "These mentally unstable people know where they're going. They're not going to a place where a bunch of people with guns are going to shoot them."

The presidential hopeful will be at Barnes & Noble in Chattanooga Sunday afternoon for a book signing. He spoke to the Times Free Press about a number of things Thursday, including Russia's intervention in the Middle East, how to address gun violence in America and the importance of Second Amendment rights amid last week's Oregon college campus massacre.
