I'm not suggesting a ban; I'm simply commenting on the posts of others.
"If his Mum didn't have a gun, he'd just have got one from someone else" doesn't wash with me. Everyone gets pissed off at some point; those with 'more issues' are, IMHO, more likely to do something like Newtown if it is as easy as it appears to be to get weapons in the US. If it is a bit more difficult, it might be less likely to happen. That, however, is only one side of the arguement. No doubt, if everyone at Newtown was armed, it may not have happened either.
That said, it doesn't affect me. I sleep easy at night knowing that it is most unlikely that I am going to be a victim of gun crime - whether legally owned or not. Moreover, I have already indicated that this issue needs to be resolved by those in the US, and I will accept whatever they choose - because I can't do anything about it.
