When talking to a university student in Germany, it was not an uncommon occurrence for 9/11 and government conspiracies to be mentioned. Implicit behind these seemingly sincerely held beliefs is the assumption of an all-powerful government capable of pulling off elaborate, precisely-timed plots with scrupulous attention given to the last detail.
In other news, Osama bin Laden still lives and the DMV still sucks.
