and if I can ever get the damn thing to work, all firearms everywhere in the world will simply disappear.

Of course, that will just be a good start. Then I'll have to develop a spell that will stop the manufacture of any more firearms. Finally I will have to work on one to make all swords, knives, clubs and archery equipment disappear. We will all live in a peaceful utopia if I succeed.

Unfortunately, I keep hearing rumors that the evil NRA has a magician working on a spell to counter mine.

but you do have a valid point to a degree. I always found it odd that it is easier to carry a gun (and legally buy one) in places you are least likely to need one (like Vermont and Wyoming) and almost impossible in places that you do (like Chicago and USVI).
