Ask Bradley Manning how that whistleblowing thing works out. I think it's important to realise doing things like that, whether ultimately for the good or the bad, comes at a huge personal risk.
To be fair Bradley Manning was prosecuted because he bonded (they had very long chats) with the guy who was supposed to relay that information. If you read the chat transcripts you can tell that Manning was very troubled at the time and wanted someone to talk to. IMHO this does not necessarily apply to someone who works at the DOJ and uses an anonymous channel to submit confidential documents to e.g. Cryptome
"Manning and WikiLeaks were credited as catalysts for the Arab Spring that began in December 2010, when waves of protesters rose up against rulers across the Middle East and North Africa after the leaked cables exposed government corruption" [1]
Manning and WikiLeaks may have been credited by some as catalysts for the Arab Spring, but they were not.
Mohamed Bouazizi's self-immolation was the catalyst for the Arab Spring. It's not as if Tunisians needed anyone to tell them how corrupt their government was. Once Tunisia looked like it might fall, revolutionaries in other countries started planning their own protests.
Amnesty International are one of the organisations that credit Wikileaks as being a catalyst for the Arab Spring.
"One example highlighted by Shetty was Tunisia, where WikiLeaks revelations about Ben Ali's corrupt regime combined with rapidly-spreading news of the self-immolation of a disillusioned young man, Mohamed Bouazizi, to spark major protests." [1]
