There is an article there discussing the rise in concealed-carry permit applications in Tennessee, following the rise in the Memphis crime rate in recent years. This is the best article I've seen outisde the gun enthusiast press. They give fair treatment to the reasons why most people who choose to get a carry license do so. There's a good description of the training process, and what it's like to go through it. It talks about safety, liability, and consequences. There is a sad dearth of this kind of work in the mainstream press.
Two key quotes:
"I tell my students: 'Don't do that. If you're defending your life or family's, OK. But don't do that.' I'm sure that man meant well, but don't get involved. Be a good observer and write down the license plate number."
A street vendor in Frayser, TN intervened in a bank robbery. Bad idea. A license to carry isn't a badge.
"You need to own up on the front end, that if you carry that gun you're willing to shoot somebody,"
If you can't handle that responsibility, then this is not for you.
