The military has restricted access to the Bradley Manning trial. So much so that no recording devices were allowed into the court room, and many journalists have been forced to take notes by hand! Further no transcripts were released.
Thankfully audio of Bradley Manning's recent testimony at a pre-trial hearing was released by unknown persons and it has since been published by the Freedom of the Press Foundation. In the testimony Bradley Manning expresses in his own words the importance of his actions, and he has shown that he is indeed a heroic whistle-blower.
