I try to look at all things rationally when it comes to things like this. I like to remove politics from it and just believe it was a guy that was deeply disturbed for one reason or another and that he snapped and planned (very well I might add) an extensive way to get back at society as a whole through the use of larger then life means (add a couple of explosions and I think he would have done that.) All that said I can not overlook the idea that it was in fact a politically motivated job or at the very least allowed by someone in power, I try not to be a conspiracy theorist but in times like these I find it hard not to.
1) The amount of firearms, ammunition, electronics, the amount of money needed to rent out two rooms at a high end luxury hotel, to transfer $100,000+ more money to an offshore account for his girlfriend, is an awful lot of money for a retiree.
2) The fact he was able to rent two rooms in a high end luxury hotel and not have some sort of suspicions raised is a bit alarming.
3) The fact he was able to move that large amount of ammo and weapons into the rooms as well as establish electronic equipment.
4) The fact that many of the firearms were legally obtained and were "Modified" weapons that were not originally intended for auto fire but had been modified with "bumper stops" which made them more rapid fire then without.
5) The fact that the subject had 0 known mental illness's, 0 arrests, 0 signs to anyone that he was having a mental issue or come apart, and the fact that he has had 0 work place incidents reported against him.
In other words we have a guy that is retired spending a great deal of money and time and effort, a hotel that lacks basic understanding of security apparently or at the very least checking to see why a man needs two rooms and enough electronic equipment to put the CIA to shame, and a lot of modified weapons that are at this time being said to have been bought legally along with large amounts of ammo.
PLUS lets not forget that no sooner did the incident happen that the Democrats along with Hilary pushed to have Congress reintroduce a bill that would have started a chain reaction against the Second Amendment.
All this put together makes me believe this was done in order to bring power to the anti-gun movement as well as the Liberal anti-2nd Amendment movement.
This is just my opinion though...and like butt holes everyone has them and they all stink so just remember that.
