Amen. The same statements could be made about cars, or matches, or a can of gasoline ... or about any number of other devices which imbue their owners with great responsibility. Taking the discussion nuclear is just hyperbole.

And yes, it is a sticky constitutional issue. I don't think the Supreme Court has touched a 2nd Amendment case since 1933 (I think), when it ruled an individual did not have a constitutional right to own a sawed off shotgun, because it was not a weapon used by or practical for the military. That one ruling is the cornerstone of all future gun control efforts.
And I am bowing out too ... I respectfully agree to disagree.
