BINGO
This could be how it went down ... not feeling comfortable with the lone wolf or sudden mental illness theories.
Paddock either targeted or befriended by jihadi elements already in country. Wife possibly a conduit or entirely uninvolved as she claims.
Jihadi elements have work at the hotel. If Paddock is a willing participant, they all co-operate in moving weapons into suite. At some point Paddock is eliminated. If he is just stalked and never knew of the plot (or the guns) then he was overpowered at some point by guys he thought to be room service.
They carry out the attack in the ten minutes as reported, and shoot the security guard through the door. He limps or crawls down the hallway, gets taken to safety and nobody has eyes on the hallway for some period of time, conspirators in hotel service uniforms or other plausible dress move to stairways and pretend to be trapped or hiding from nearby gunfire they heard, when law enforcement reaches their position. At this point they are assured it is safe to leave and they leave.
Hotel management may never have known, collusion might only reach a supervisory level. Same as some airport breaches of security in baggage areas.
Paddock might have been a co-conspirator after hearing the spiel, or he may never have known a thing about it, just the person unlucky enough to be in the desired suite (the inside plants would find out the reservation info, maybe he was chosen because he reserved for several days, any floor might have done as well).
I don’t give much credence to the far-left political whacko theory for two reasons, Paddock doesn’t seem like that sort of person and the actual fans in attendance mostly non-political types, young people out for a good time.
The scale suggests Islamic terrorism. The wife’s country of origin may be significant but I tend to think it’s just a coincidence meaning nothing, she seems to be from a mainstream Filipino background (i.e. Catholic).
