Liar In Chief Plays Dangerous Trump Card To Stop Litigation:
"Facing a wave of litigation ... the Bush administration is increasingly turning to a legal tactic that swiftly torpedoes most lawsuits: the state secrets privilege ...  The privilege has been asserted by the Justice Department more frequently under President Bush than under any of his predecessors ... Under Mr. Bush, the secrets privilege has been used to block a lawsuit by a (FBI) translator ... who was fired after accusing colleagues of security breaches; to stop a discrimination lawsuit filed by Jeffrey Sterling, a Farsi-speaking, African-American officer at the Central Intelligence Agency; and to derail a patent claim ... evidently to guard technical details of government eavesdropping ... if the government is not truthful, plaintiffs will lose and there's very little chance to straighten it out ..." (emphasis added)

These days, of course, it's not a matter of "if the government is not truthful" but rather how outrageously untruthful the Bush government is in any given circumstance.  Make no mistake, Bush is invoking the state secrets privilege to hide his administration's crimes, errors and incompetence - NOT to protect national security.
