I’ve written often about guns and how they tend to make ordinary confrontations more lethal. One tragic example the other day from my tiny little hometown of Yamhill, Oregon, population 1,000: A drunken man was leaving the pizza parlor, and other patrons didn’t want him to drive while intoxicated, so they tried to take his keys. He pulled a gun and started shooting. A Good Samaritan rushed over to help and was shot, plus the alleged shooter managed to shoot himself. As Yamhill tries to heal, I wish the N.R.A. would understand that guns can turn ordinary altercations into tragedies like this.
