> As a member of parliament, he would only have immunity in Australia from police investigation and arrest Try telling that to Craig Thomson, MP. IANAL, but Parliamentary Privilege only buys you some freedom of speech (if you play your cards right), and some protection from civil arrests (i.e. being told to go to court for a civil matter within 5 days of parliament sitting). Note the civil bit - anything the police are investigating will not be civil. "Civil disobedience" can still be criminal, thus not a civil matter. Leaking Top Secret information will certainly push the envelope on freedom of speech, and nothing will protect him from any prior criminal charges.
