The killing of innocent children at the school shocked the nation and prompted a number of politicians including President Barack Obama to call for a ban on assault weapons and ammunition clips that allow the rapid firing of multiple bullets.
Rather than tighten gun ownership restrictions, the powerful lobby for gun rights, the National Rifle Association, on Friday called for armed guards at every school.
D.R. Woody was one of those able to purchase an assault weapon at the Kansas City show on Saturday. He bought the gun for target practice because he is concerned they soon will be banned. "I didn't expect to find one. No gun stores have them," said Woody of the AR-15 type of gun.
The story was the same in Allentown, Pennsylvania, where Shirley Donley, a gun shop owner from nearby Quakertown, had an endless stream of customers. "Everybody wants assault weapons," she said, adding that she had sold more than 100 of that type of gun since the Connecticut tragedy. "I'm sold out."
Assault weapon is a broad term commonly used to refer to semi-automatic or automatic weapons that can fire multiple bullets rapidly. From 1994 to 2004 certain assault weapons and ammunition clips of more than 10 bullets were illegal.
