Perhaps, though people are often too quick to conclude that crises are staged just because governments are prepared to quickly exploit a particular category of crises to push a pre-existing agenda with motivations only tangential to the crises, and ultimately the debate over whether the crisis was staged detracts attention from criticism of the response (especially when the crisis wasn't staged, and the claim that it was staged can be convincingly rebutted and used to discredit those questioning the response.)
See, e.g., 9/11 truthers.
