Thanks for opening up. How much weight do you put in the theories (stated in other comments) that Adrian thought he was under FBI surveillance, and reported Manning's leaks out of fear?
Honestly, I can't comment on that. I know Adrian was a SERIOUSLY good social engineer, and a fair to middling hacker. The chat logs show Adrian going very in depth with Chelsea, so if he thought the FBI was watching, he was purposefully giving them a good show.
