Whistleblowing isn't illegal, though. Of course part of this debate is specifically with the one individual who is currently detained (who probably supplied a fraction of a percent of the amount of information Wikileaks has); is he a traitor or a whistleblower? If he was lying, or leaking false information, I think that's one thing. If he's providing accurate information, then IMHO that is whistleblowing and he should be protected. Clearly we will disagree on this. :)
This isn't real-time data being provided to our opposition. In this age, 24 hours is a long time, and we're talking about information about events that happened weeks, months, and even years ago. That's why I disagree with the notion that Wikileaks is somehow jeopardizing lives.
