This market resolves only to the name of a specific person, and only if/when historians are substantially more confident in the correct answer than they are now. (If they're confident that it was none of the named people but don't know who it was, I'll resolve to "other". Arbitrary names added without any reason to believe it might be that person will be ignored.)

This refers to whoever fired the lethal bullet, not anyone else behind that decision.
