What's the difference between Wikileaks releasing secret documents and newspapers doing the same? Will news sites not get into trouble for reporting on their contents? Why is Wikileaks being singled out for blame?

1. Wikileaks cooperate heavily with its sources.
2. Newspapers just get documents from its sources, without cooperation (asking, begging and trying to influence sources)

No. 1 is punishable by law in USA, and many other countries.
No. 2 is not punishable by law.
