I was just looking at the news stopping people from legally purchasing weapons that are on the terrorist watch list. I'm not with them on this for several reasons. The AG has already said, along with others, that "tea party" people, some Christian groups, etc. are "terrorist." Also, I've been hearing news stories here and there about people who have never been in any kind of trouble, and have never been affiliated with anyone or group that has been labeled a "terrorist" organization, have been showing up on this list.
Now, if I found out that I couldn't purchase a weapon legally, what's to stop me from buying one illegally? The LAW?
These laws only effect law abiding citizens, since they are the ones who normally try to purchase weapons legally. Criminals and/or terrorists get theirs illegally.
