Don't joke about hand grenades and such. Not that long ago Scalia, bless his wizened little soul, was saying that it wasn't clear to him what limitations would make sense under the recent court decision. Specifically, he said, if the intent (so much garbage flows into that particular sewer) was to preserve the right to carry weapons, then he didn't see why citizens shouldn't be able to carry things like RPG launchers--they are, literally, born by the person, so why not?
