“...he 2nd Amendment doesn’t guarantee anything.”
Certainly it does: although The Second Amendment does not ESTABLISH a right, it does guarantee ACCESS TO a preexisting right. In that capacity, it serves exactly as The Founders intended; quashing the aspirations of control freaks like Obama who would rather there be no impediment to government being the regulating body that decides what rights you may access, when, and to what extent.
Kudos to the Ninth Circuit for proving — yet again — that even a blind squirrel can find a nut once in awhile.
