This is ballsy stuff. I think the people who did this are too young to understand they can indeed go to prison.
Especially now that they can shop around for a legal jurisdiction, and extradite internationally as needed to "send a message."
Not that you'd really need anything like a trial any more...
Officially determine this latest stunt is a "threat to national security" (Hmm...secret communications between two national
policy agencies compromised? Yep, we can call it that!) and all those nifty new indefinite ( and optionally secret!) detention without charges or trial
powers can be invoked.
And likely will be.
Right now, I think the risk of getting arrested is the least
of their worries. Especially as this latest escapade has made it somewhat "personal" as db90h so aptly pointed out.
Too many people are laughing about it.
And the whole point of authority is making sure nobody ever laughs at the wrong time.
