The whole situation was crazy; to look at the video, there were swat teams at other hotels, reports of shootouts where people were killed, and the main shooting... oh ya, and the video of the apparent helicopter shooting.
I doubt we will fully understand all that was going on, above and beyond the shooting itself.
I agree, we will never really know what the hell happened, but there is definitely more to the Paddock story than the public has been told.
I tend to agree that there was a saudi arabian connection.
With all the evidence that I've seen, it really looks like Paddock was a gun dealer.
Without taking anything away from your points, it seems the good money is that the whole event was contrived as part of an assassination attempt of a Saudi Prince. If you look at what happened in Saudi Arabia, around the same time there was a mess of arrests, and still, they are still in what could be considered a civl war.
Prince Salaman is the one that the west should support. He wants women to drive and hajib optional, etc... (progress) and an end to jihad citing that the world knows of allah and there is no longer the need for (insert koran reference).
