Frankly, looking at some of the Wikileaks documents marked Secret I can only conclude that many governments go way too far when it comes to identifying and defining what they think the population shouldn't know or see.
Do Journalists have any obligation or responsibility to protect their sources? Yes they do. If they didn't no-one would ever come forward to expose corruption, abuse of power, fraud, etc. from high places. We need them to be able to do that in order to protect, maintain and keep our democratic system strong.
For that reason, our democratic system has a duty and obligation to protect any Journalist who is acting in that tradition from persecution and abuse. Not doing so weakens our democracy and enables corruption.
And Governments around the world want to suppress them, scapegoat them, kill them. Corporations they do business with are withdrawing services they have legitimately paid and contracted for.
And Assange has been personally victimized with specious charges of "sexual assault", the timing of which make them appear to be more about discrediting and smearing him, than any actual criminal act on his part.
Why is all of this happening? Because Assange and Wikileaks are doing their job!
The end result of which is the potential embarrassment and exposure of abuse of power, corruption, immorality and unethical behavior at the highest levels of the government and corporate world.
In other words, this is what these Governments really consider a crime and "treasonous":
If you want to help Wikileaks and have a Unix box, mirror their site to ensure the material remains available.
Let's protect Free Speech and an Independent Media that acts as a Watch Dog over Government and Corporate corruption and crime!
