I wish that no citizens had guns but:
I taught in a low-security corrections institution for almost 20 years. Before I taught there, I thought that passing a law against citizens having guns would work. Now I know that there are so many ways to get a gun, legally and illegally, that I realize it could never work.
During class breaks, the men would be casually discussing their guns and where they got them (btw, none of these men had committed violent crimes) and for years, I would ask if they thought that a law could stop the general population from having guns. They would fall over laughing. It seems that making gun ownership illegal would hardly make a dent in the criminal world's access to guns. And these men had never used a gun in a crime! Can you imagine how much easier it is for the really rotten people to get one?
I don't think that the hunters of the country would go along with giving up their guns either and of course if someone could still get a rifle, he could do some serious damage to people as well. I've always felt that Americans have so many guns because our ancestors who conquered the frontier had to have them and owning guns is more acceptable here than in some other countries.
Like most of you, I wish that people who had no business with guns didn't have them. After working in the CI, though, I can see that that will never happen.
