Although the two are not necessarily mutually exclusive. In a situation involving armed self-defense, you can be both lucky and smart. But always remember that you can do everything right and still end-up deader than a doornail. And you can do everything wrong and prevail. But not having a gun when you need one? That’s not smart and has nothing to do with luck—unless you’re unlucky enough to live in a city, town or state where the government doesn’t respect the non-infringability of your right to keep and bear arms. See how that works?
