You picked a terrible example, as he did restrict guns on a number of occasions during the terms. The fact that the gun control lobby gave him an "F" rating is because the fact that they want too much and are never happy with just a little.
It certainly didn't make Democrats reconsider taking the rights of millions of Americans away after they lost the midterms following the 1994 Federal Assault Weapons Ban.
I would be interested in hearing that argument. On the surface it appears to be an argument of creating special privileged groups who are the only ones who have freedom of speech or the ability to avoid having troops billeted in their dwellings. Maybe that would lead to more safety?
That makes me think of the society from Heinlein's Starship Troopers where you had to earn citizenship through civic duty. He certainly portrayed the non-citizens having a safe existence (during peacetime).
