Things don't add up, that's for sure. A lot of people think it was either bumpfire, an FA mod or a crank mod due to the fact that the speed of the bullets fired didn't seem consistent.

The false reports of multiple shooters could be due to echoing of gunfire, leading people to believe there was more than one shooter. The scanner audio does suggest there were multiple shooters though, so I am conflicted about that. It could very well be a confusion tactic.

I think the biggest thing that throws me off is indeed the supposedly massive amount of guns and ammo found as well as the rest of the setup in the hotel suite.

The floor shown in the picture is more likely to be around floors 16-18, the hotel has 43 floors total. Then again I've also read that the layout of the hotel is odd and that it skips numbers (?). The flashing in the picture was also present in later live footage on FOX I believe, so perhaps it is not muzzle flashing. Ofcourse I could be wrong about any of these things, just adding my two cents.
