There have certainly recently been what appear to be stunning lapses of judgment by private citizens with guns. There was the incident with an armed pharmacist alluded to by Glenn. Then there was this little incident in Boise --

In any case, those States with training requirements are unlikely to abandon them. And the States without training requirements reduce the likelihood of nationwide recognition of CCWs, either by voluntary State action or by federal legislation. For example, the OP's Georgia permit isn't honored in South Carolina because Georgia has no training requirement. And Nevada just dropped Utah from it's list of State CCWs it honors because Utah doesn't require a demonstration of actual shooting proficiency (which is why 10 days ago I was in Reno taking the class, qualifying and applying for my non-resident CCW). Some may object, but it's still a fact of life.
