Training is the issue. I have long posted on this and agree with JSD that I want more assurance that people can hit what they're shooting at, and not me. I often am a bit discomfited at the people who post: "Yay, I got my permit!" which sometimes sounds to me like: "Oh, wow, I can carry a gun!". They rarely mention any serious training which they might have received, which tends to make me think they haven't received any.
So, let's look in the mirror, here. How many of us have borne the expense of serious training? I don't mean the minimal CCW stuff, but real defensive and tactical training. I have admitted earlier that I carried for years with no formal training. Eventually I did incur the expense and boy, was I surprised at what I didn't know.
I think "peer pressure" might be the way to go, here. Get training yourself and then encourage other carriers to do the same. The pride, confidence, and comfort with arms that you have should be apparent to others. Just my feeble opinion.
