Las Vegas Shooting, Steemit Community, What is your Theory?

On October 1, 2017, Stephen Paddock, a local Nevada resident opened fire on concert goers at the Route 91 Harvest Festival from his hotel room on the 32nd floor of the Mandalay Bay Hotel. He killed 59 people including himself and injured over 500, but is it possible that Mr. Paddock, a 64 year old, multi millionaire entrepreneur and gambler acted alone? The incident is the deadliest mass shooting committed by an individual in the United States. The crime reignited the debate about gun laws in the U.S., with attention focused on bump firing, a technique Paddock used to allow his semi-automatic rifles to fire at a rate similar to that of a fully-automatic weapon.
To me something is clearly wrong here, how did this man plan this entire rampage solely by himself? In all, 23 firearms, a large quantity of ammunition, and numerous high-capacity magazines capable of holding up to 100 rounds apiece were found in the suite. The firearms included AR-15 variants manufactured by Daniel Defense, FN Herstal, and Lewis Machine and Tool Company, as well as Kalashnikov and AR-10 pattern rifles. Two of the rifles were equipped with telescopic sights mounted on bipods. Audio recordings of the attack indicated that Paddock sustained a high rate of fire, using either a fully-automatic weapon, or a semi-automatic weapon utilizing devices to simulate fully-automatic fire. Bump fire stocks were found on twelve of the guns, which allowed for the recoil to actuate the trigger at a rate of 90 bullets in 10 seconds. The Bureau of Alcohol, Tobacco, Firearms and Explosives determined the guns were legal and legally acquired by Paddock. How did he possibly get all of this into his room? Ok maybe they were in bags and the busboy/bagcheck guys simply hauled them to his room without asking questions as I am sure some very strange things are brought to hotel rooms in Las Vegas and they do not use metal detectors...But even so how did housekeeping not notice something strange unless he never allowed them in? What about his girlfriend being sent to the Philippines weeks before after wiring 100k to her there? There are so many unanswered questions I am interested to hear any theories from the Steemit Community?
