That's because Second Gunman Theory Disorder is a fairly common condition. When a great crime occurs and only one perpetrator is involved some people tend to gravitate to the delusion that due to the disproportionate relationship between the perpetrator and the importance of their victim or number of victims, there must have been more than one perpetrator involved. Evidence or lack of evidence notwithstanding.
Second Gunman Theory Disorder is impossible to treat as far as I can tell. No amount of evidence can dispel the delusion once it set in. The best thing to do is just dismiss people with this condition out of hand. You'll only frustrate yourself and anger them if you try to argue with them.
Well I don’t necesarily subscribe to a second gunman theory.
I just don’t think that it has been adequately demonstrated that there were not other persons in the room with Paddock, or that he killed himself.
And what is still missing is a motive that is consistent with the fact patterns of his life.
It is intellectually lazy to assume, in the absence of available evidence, that Paddock was simply a crazed loner who decided to go on a shooting rampage.
I've been called crazy for believing this, but I am entitled to believe it and I continue to believe it. The SS would NEVER admit it for obvious reasons.
