2) Killing Julian Assange would send a message: Julian Assange is not an American citizen and he has no constitutional rights. So, there's no reason that the CIA can't kill him. Moreover, ask yourself a simple question: If Julian Assange is shot in the head tomorrow or if his car is blown up when he turns the key, what message do you think that would send about releasing sensitive American data? Do you think there would be any more classified American information showing up on Wikileaks? That's very doubtful. Do you think the next cyber punk who thinks it is a game to put classified information on the web would think twice? Yes, you bet. Legally, we may not be able to do a lot to Assange since he's not an American, but killing him would do more to protect our classified data than any new security system.
