Perhaps not all information should be released, however, in the end perhaps it's only whistleblowers that can uncover certain things and force decision makers take back certain laws. (Fictional?) example with body scanners: The company making those has a real interest in the terror threat never going away. The shareholders expect that. The politicians get elected with money from security companies. Thus: The terror threat will never go away. UNLESS a whistleblower shows the truth and the population gets upset. Whistleblowers are important for democracy.
