More on whistle-blowing, from the BBC:
Whistle-blowing site Wikileaks is getting legal help to fight an attempt to keep it offline.
Freedom of speech and digital rights groups plan to argue on its behalf at a legal hearing on 29 February.
The hearing will decide whether to continue a court order that removed links to some of the Wikileaks sites from the net's address books.
The order was sought by Swiss bank Julius Baer after internal documents were placed on Wikileaks.
