What is the incentive to claim the hitman-theory is baseless conspiracy?

Hm. To throw us off the scent if it is not baseless? I have no idea what happened or why, but that guy seemed far too calm the entire time to have not been some kind of pro. Perhaps he was under mind control? At this point in our currently very surreal world, no explanation seems preposterous to me. I'll wait and see, but will not believe a word of the official explanation, especially if it is very simple.
