There's no lack of powerful people who would like just that; from the president of the USA down. If they are impotent about it, it is because it is not a crime. Maybe it will become one, as a consequence of this global embarassment; that is possible. But there are millions and millions of smaller fish than Assange, who engage in leaking and hearsay, rechilut and lashon hará every day, with or without willfully leaked documents, be they private or not. Can the world put them all on trial? How about people in any army, any office, having access to private documents, putting them online. This is the essence of the cyberspace: it is promiscuous. And there's hacking -which is penalized when it is not in a state's interest, and used as an intelligence tool, like Stuxnet or Stuxworm or whatchamacallit...- It's a huge mess. Regards, Fortuna.
