I would like to make Yoichi Kobayashi’s cold-flaming crystal skull the executor of my estate.
… but just a reminder to my American readers: We already live in this reality. This country isn’t just full of guns; it’s full of ammunition. If you have access to even a single bullet, you are $10 and a trip to the hardware store from making a wonderfully lethal weapon: unserialized, untraceable, highly concealable, nearly foolproof. You won’t be doing any civil massacres with a hardware-store slam gun, but you can mostly definitely kill the guy standing in front of you with little effort.
The reason no one will shoot you today is because no one feels like shooting you today.
