But as even top intelligence officials have acknowledged, overclassification is rampant in government. Much basic information, without which effective national security reporting would be impossible, is reflexively classified, whether or not it poses any realistic security risks, and reporters routinely discuss such information with sources. In practice, that means the government can pick and choose which leakers to go after—and which ones to wink at, because they're serving the administration's interests. No doubt, the government does have an interest in—and an obligation—to protect legitimate secrets, but an aggressive campaign that targets reporters and subjects them to broad and secret intrusions (and maybe prosecutions as well) will undermine a necessary check on government power and prevent the public from learning crucial information about what is done in its name.
