Julian Assange on Wikileaks, Bradley Manning and the Emerging Surveillance State

JUAN GONZÁLEZ: Bradley Manning, the U.S. Army private accused of leaking hundreds of thousands of classified documents to the whistleblowing website WikiLeaks, may testify today at a pretrial proceeding for the first time since he was arrested in May 2010. Manning could face life in prison if convicted of the most serious of 22 counts against him. His trial is expected to begin in February.
