"The shooter filmed himself for some reason. That’s key I think."

That's one thing that nudged me further towards the ISIS-related theory. That's part of their MO. There are still huge gaps to fill but:

ISIS claims involvement.

ISIS called for violence in Vegas.

ISIS targets events like music concerts and places frequented by tourists.

The shooter had a newfound familiarity with high-powered weaponry, explosives, and weapon-altering methods, as if he had recent training.

There was a lot of planning.

And, finally, no better theory has emerged.
