Say the bullet can be stopped by Kirk's moose-neck. (It wasn't. But for the sake of holdling that as a one's conclusion--)

To get to that point, a person making that case has to accept that Tyler can disassemble a rifle faster than any recorded time (he's an Olympian and should've been in the Odyssey) *or* Tyler put the rifle in a diminsion that's not his hands or pants or backpack *or* all videos showing Tyler on the roof were faked within minutes of the shot *or* the guy on the roof without a rifle wasn't Tyler and Tyler shot from somewhere else.

Those are the only possibilities minus one. (Tyler didn't kill him. Wanted to? Supported the thought? Would've tried? Knew it was the day? Yes. Obviously. They call that a patsy.)
