In what he called the happiest day of my life, National Rifle Association C.E.O. Wayne LaPierre marked Valentines Day by marrying his longtime gun, an AK-47 assault rifle. Mr. LaPierre grew emotional as he reminisced about meeting the firearm at a gun show in Alabama in 1991. The chemistry between us was amazing, he said. Our first weekend together, all we did was shoot. Marriage between a human and a gun is not legal in most states, a situation that Mr. LaPierre bemoans: For a lot of N.R.A. members its the only intimate relationship theyre capable of. The wedding ceremony was attended by twenty-five of Mr. LaPierres guns and over two hundred members of Congress.
