Conceal carry is certain not a cure for all things. But then nothing is, the one thing that is tough to learn and maybe impossible to teach is to know "when" to use a firearm. I like guns, I have a conceal carry permit I almost never carry, I seldom go places where I think it might be of benefit to me or my loved ones. The only thing I can think of that a conceal carry firearm would be of benefit in a drive by shooting would be if I were able to achieve cover and make certain that they don't stop and come over to make sure they got me. In that case I wouldn't go quietly, might never cut a hair on them but it wouldn't be for lack.of trying. If someone want to carry I am all for them doing so, do it legally, learn when, where and how to use it well. FWIW the only reason I have ever carried a handgun is a rifle isn't always practical.
