Wictor operates strictly on information he can research and substantiate on his own.
From pictures of crime scene (hotel room), he thinks Paddock had all rifles loaded and stacked on chairs. Also thinks Paddock had the pistol to use if someone came in the door.
His theory is Paddock emptied rifles he was using and then gathered up 4 more loaded rifles and wanted to carry them (in bear hug fashion) to the room with the other broken window.
Thinks Paddock was holding the pistol while doing it, so pistol pointing up. Paddock was wearing thick shooting gloves meaning the pistol was more sensitive to trigger pressure. Paddock slips while walking on empty casings and shoots himself through the chin.
Pictures of rifles in odd positions around Paddock's body, and bleeding pattern are the basis for his theory.
Not saying this is true. Just saying he won't make a theory based on unknowns. Giving the knowns, this is what he thinks.
He doesn't entertain what ifs. He's upfront (and anal) about it, so I can understand where he's coming from, although I think there are other factors yet to be divulged.
