Americans own an estimated 300 million guns. It's a level of gun ownership that no other country in the world comes close to matching. It's also a source of controversy in the U.S., where groups on both sides of the issue seem to have dug deep into the debate.
Texas state Rep. Wayne Christian was born two blocks from where he now lives in what is called Deep East Texas.
"We were not wealthy people, [we were] common laborers, but that was typical in rural East Texas at that time," he says.
When he was growing up, Christian says, by first or second grade, an East Texas boy would accompany his father or grandfather on a hunting trip. But before a boy got a gun, he had to learn how to act — how to address the other men respectfully, to watch how it worked.
