If you've got an hour to spare watch this "conspiracy theory" documentary about 9/11. It raises a lot of questions about the official version of events that led to the collapse of the twin towers and what happened in the aftermath. For further reading Noam Chomsky has some theories about the US government, if not orchestrating it, then letting it happen.
Isn't it interesting that anyone who questions the validity of what we're told to believe is labelled a conspiracy theorist. Not, "maybe this person has a valid point" or "hey, that
is worth investigating". Even the term 'conspiracy' has an air of "paranoid psycho" about it. How is anyone meant to challenge conventional viewpoints, when a government lies and it is "official", but someone disagrees and it is "conspiracy".
