@hightor,
By all means let's bring back the militia.
Militiamen have the right to have machine guns and grenade launchers (and the associated ammo), and the right to keep them at home.
I'd love to have a closet full of 84mm bazookas. So much for bad guy body armor. One direct hit to the chest and they'll be scraping chunks of bad guy off my walls and ceiling with a spatula.

However, the Second Amendment protects the preexisting right to keep and bear arms. That preexisting right includes the right of NON-militiamen to have guns for their private self defense. So don't think that bringing back the militia means you'll be allowed to disarm non-militiamen.
