BRYAN, Texas -- As President Barack Obama urges new gun restrictions in the wake of the Connecticut school massacre, the National Rifle Association is calling for armed volunteers in public schools.
It has set up another political debate over gun violence.
Yet gun enthusiasts like Adam Lanza's mother complicate a gun-owning narrative that critics sometimes simplistically put at the feet of a powerful lobby and caricatured zealots.
Authorities say Adam Lanza used his mother's high-powered assault rifle and a pair of handguns to kill 20 children and six adults.
Nancy Lanza was among the millions of armed U.S. citizens whose numbers far exceed gun owners anywhere else in the world.
Blake Smith, a Texas gun owner, shoots for sport but says he's not a fanatic. He says "everybody has to have their Zen."
