I have been following this horrific act in this forum, in the media and on other forums fairly diligently. There seems to be a number of unanswered questions, and about 15 conspiracy theories for each. The discussion here appears to me to be relatively subdued and tame, not that I am a fan of conspiracy theories, but there seems to be a number of things that just don't jive. Granted, this a strange guy doing a strange thing, but still.
First, the information released has been exceptionally sparse. We had 911 and Boston Marathon CCTV images relatively quickly. Here we have nothing. We are told that he acted alone and he is dead, so why the blackout? It is near guaranteed that there will be some things withheld, but there has be almost nothing.
Second, the assertion that he had an escape plan, but cannot be told anything further. If the perp is dead and there is no one else of interest, why conceal that?
Third, why a firearm count of 23 instead of three? He was obviously intelligent and meticulous. Why risk the whole operation? If he did have an escape plan, it would be interesting to see the plan for quickly removing those firearms. Presumably, at least one of them would be traceable to him.
Forth, given the amount of ammo this guy went through, he should have been "ankle deep in brass". Not literally of course, but the crime scene does not appear like that at all.
Lastly, the entire story of the encounter with the security guard seems off:
Initially he was the hero who ran up there, got shot, and compelled the gunman to off himself. A week later he is there before the shooting, perhaps triggering the beginning of the shooting rather than ending it. Two hundred rounds fired and he has one non life threatening injury. Just that event should have dispensed a lot of brass.
He is the only witness we know of. Why have we not seen him 100 times on video?
How can someone shoot 200 rifle rounds through his hotel room door and yet we have not heard a peep from anyone on thee same floor with some type of damage in their room, or at least having heard something?
I don't have my own conspiracy theory, in part because there is so little information available. The strange thing is that each bit of information seems to be questionable in one way or another.
