Well before the tragedy it appears that Newtown, CT, had a problem with guns, too much guns and no regulations, according to this New York Times article.
Recent efforts by the police chief and other town leaders to gain some control over the shooting and the weaponry turned into a tumultuous civic fight, with traditional hunters and discreet gun owners opposed by assault weapon enthusiasts, and a modest tolerance for bearing arms competing with the staunch views of a gun industry trade association, the National Shooting Sports Foundation, which has made Newtown its home.Target practice was done in the wild as there was not enough shooting ranges in the vicinity to welcome all the gun enthusiasts:
The gunman’s mother, Nancy Lanza, had collected several weapons, including powerful handguns and a semiautomatic rifle that she and her son, Adam, were fond of shooting, and it remains unclear where they took their target practice. Much of the gunfire and the explosions reported by residents to the police in recent months came from a spot less than three miles from their house. Police logs identified the spot as one of the town’s many unlicensed gun ranges, where the familiar noise of hunting rifles has grown to include automatic gunfire and explosions that have shaken houses.
“It was like this continuous, rapid fire,” said Amy Habboush, who was accustomed to the sound of gunfire but became alarmed last year when she heard what sounded like machine guns, though she did not complain to the police. “It was a concern. We knew there was target practice, but we hadn’t heard that noise before.”
