Is it just me, or does this paragraph display a worrying tone of increasingly dangerous weapons? First a pistol, then a silencer (to use on a rifle range? Go figure), then a 30-cartridge magazine for a semiautomatic rifle, then a privately-owned machine gun, then a sawed-off shotgun...
I can see the next paragraph: "Modifying my hand grenades is TOTALLY outlawed now, I need a special permit for my APC, My Abrams' tank has to be registered, and don't speak to me about the mess I had with that H-bomb..."
Really, having a pistol, a silencer, a semiautomatic with 30-bullet clips and a machine gun should be enough no matter how p*ssed off you are. Do you REALLY need that sawed-off shotgun as well?
