"It's always too soon to talk about gun control"

...
And no, I don't expect everyone to just hand over their guns; I'm expecting that the actual result of such efforts would be a slow encroachment on the idea that having a gun is a right and that it is instead something that becomes a privilege showing a great degree of trust by society (as facilitated by the government) in the good sense and judgement of one authorized to carry a gun. ...

There's the rub - in the USA, having a gun (or any other weapon) is a right, protected by their Constitution.

In order to institute any sort of firearms regulation, you're going to have to either repeal or re-interpret the Second Amendment to the Constitution. This is not impossible - at least one amendment to the Constitution has been repealed in the past - but would be very, very difficult to actually do without a major shift in public opinion.
