I think this raises an issue we can't easily dismiss, how to handle whistle-blowers. On one hand they are essential to democracy, so we don't want to jail all of them; on the other they can cause great harm, so we don't want to enable all of them. How do we enable good whistle-blowers and stop the bad ones?

Let's hear serious proposals. Would a law that puts the consequences on the leaker's shoulders be sufficient? Prosecuting someone after-the-fact when, due to the leaker's misjudgment, their leak lost a war and killed hundreds of thousands wouldn't be enough. Require them to exhaust internal institutional solutions? Again, that wouldn't protect us from a leaker with bad judgment; the worse their judgment, the more likley the institution would rightly reject all the leaker's claims, leading to a leak. Rely on executive clemency?
