The Supreme Court ruled that the nfa was legal because a sawed off shotgun wasn't considered a common weapon in usage with the militia. It was that ruling that allowed them to restrict those weapons.
If another gun ban is attempted, could it be cited that an AR-15 IS a common weapon in use of the militia, and therefore constitutionally protected???
"If you remember nothing else about what Iím about to consider here, remember this: the one and only reason politicians, bureaucrats, and policemen want to take your weapons away from you is so that they can do things to you that they couldnít do if you still had your weapons."ó L. Neil Smith
