It's not a concern about maniacs hitting 18,000 theaters simultaneously, its about hitting one. Even if a single theater is attacked by one moron doing a copy cat attack, the people injured could sue the living bejesus out of Sony, and an the PR spin would be even worse than it is now. Personally, I think it should be leaked to the internet, so about a billion people can see what only a few million would have seen otherwise, and then release and uncut directors version on DVD 6 months from now after all this insanity has died down.
