You seem to make the assumption that whoever it was that were selling these shotguns would sell them to anyone that walked in. Maybe you should give people credit for a little more common sense. As things are right now, I doubt many people would sell a firearm of any kind to anyone under 18. Hardly true, Ms. Robertson. Many of us are fighting to roll back many of the laws now in effect.
All gun laws do is impede the law abiding, as was proven in Colorado.
The 17 or so gun laws those punks broke didn't even slow them down. I was a fool who trusted my fellow human beings to not steal from me as I ran into a downtown establishment for a few moments. I trust no one now. Everyone is suspect in my eyes. A couple of dollars, some change, several credit cards that were cancelled within 30 minutes, a few rolls of film and some personal items.
