A gunman goes into a church --have you heard this one? Essentially the latest headline goes: Texas church gunman kills two armed churchgoers before being killed by yet another. That's a lot of Texas church gunmen. Apparently when the shooting stopped even more worshipers pulled out their guns. Let’s see, the lesson about needing a gun to defend oneself doesn’t add up so well in this example. In Texas totting a gun to church means you have a one in three chance of surviving an attack by a fellow gun believer. Sunday's two victims were armed after all and it didn't save them. And if we think about this charitably, as we ought to because the first gunman, the troubled one, was a churchgoer himself, having a gun didn't save him either, the actual odds become one survivor out of every four church gunmen. God rest everybody's piece. So the lesson here is, don't go to church! And especially not if you are packing. If a fellow troubled soul doesn't shoot you, security will.
