"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." 10th amendment, 1791. Unless a federal amendment says the second amendment is repealed [lets hope for Christ's sake its not] the states/federal government have to allow you to obtain a gun. You see, this is why the constitution isn't a work of poetry- it wasn't meant to be interpreted, the ideals in it are fairly timeless and only recquire minor common sense edits as time goes on.
