I don't know what parts of the assassination attempt were staged or what parts, if any, were real beyond the very real death of the attendee on the sidelines.
But what I do know for an absolute fact is that cartilage does not regenerate, as anyone with a knee or hip replacement can tell you.
But hypothetically -- just for any science haters that may be lurking -- let's claim the impossible and assert that cartilage does somehow miraculously regenerate. It sure as fuck doesn't regenerate in 72 hours, which is roughly how long it took before the impossibly unbloodied bandage came off to reveal a perfectly "healed" ear.
