I firmly believe that we definitely do not know the story behind what went down in Las Vegas.
What I'm not sure of as of yet is whether or not it is being held back by authorities in an effort to aid the investigation and capture of other perpetrators, whether the authorities themselves don't know what really happened, or whether it's simply being withheld from the public for political reasons.
Whatever the case, it's my opinion there were definitely others involved, and that Paddock did not act alone. I'm starting to get the feeling he was kind of like a Lee Harvey Oswald type. He could just be a patsy.
At any rate, if history repeats itself, as it often does, we may NEVER know the truth.
