I liken LC, with no disrespect intended to the victims and family of 9/11, and only in the manner of how irrational behavior can become prevalent, to The Blair Witch Project.
And for this reason: When I first saw the Blair Witch Project in the theater on it's opening-day -- I was browbeaten into seeing it by a female that shall remain nameless -- what first took me aback, was not the film, but the mass hysteria it generated, not only in the theater, but on the internets during that time.
The film was completely fictional, and yet the amount of people that bought it right out-of-the-boxoffice and then indulged in more irrational behavior online, was stupefying.
I read many website's that claimed to show 'real' evidence that the people in the film were indeed missing; more sites by individual's that were not, in anyway related to the movie, started making their own spinoff sites claiming the very same 'evidence' was indeed true, giving validity to the fictional evidence in the minds of many.
The website' s that purposely and with full knowledge of it's fakery, purported to show actual artifacts recovered from the scene where they disappeared, and the infamous unearthed material: the video tapes, knew what they were doing, and what they were playng to. Not long after, the same spinoff sites, made by people that were never connected to anyone that was involved in the making of that movie, were spouting ridiculous endorsements of said evidence, citing: they 'knew' it was true and they 'knew' friends, or relatives of the people connected to the actors/actress in the movie.
It is not difficult to sell something to the public, and with little to no evidence to back it up. You can just sit back and then let it run on it's own and in the minds and hands of it's devout believers.
