The problem is, his definition of the 2nd amendment is that it might give some individuals the ability to own one gun and one gun only it some government bureaucrat arbitrarily decides that they have a valid "need" for the gun and which point the individual may purchase a single shot gun. One they purchase this gun, they must store the gun and any ammunition (limited to a maximum of ten rounds) in separate locked locations. They may not use the gun for self defense (that would violate the rights of criminals). The gun may only be used for target practice at government approved gun ranges, with a maximum of 50 rounds shot per year.
