The US doesn't need to have this argument again. The second amendment is not an absolute right because no right in its constitution is absolute. Nearly every amendment has had limitations and exceptions placed on it which implicitly states that each right is conditional; and more, this sets a precedent by which it can be understood that each right can have limitations imposed upon it for the public good.
The second amendment has, in fact, received the fewest restrictions on it... except perhaps for the third, since it has rarely been invoked in modern days. So it's really not as though US citizens' right to bear arms has been unfairly abrogated and thus everyone needs to stop picking on the poor little amendment that's just trying to do its job, gosh darn it.
It doesn't matter what side of the fence you sit on with regards to the necessity of the private ownership of guns. Its plain as day that there's nothing constitutionally extraordinary about looking to keep the guns out of the hands of Bad Guys. Let's stop debating whether or not a national conversation on gun control should be had. Let's try to just have one that makes everyone (except for the Bad Guys Who Want Guns) feel satisfied.
