I don't see anything here that couldn't be a fabrication on LOMO's part as part of an attempt to smear manning. LOMO isn't exactly a stand-up character, and combined with someone inside the military (which wouldn't be hard to find when the government is looking to create a scapegoat) these logs could be easily fabricated.

I also don't think that text logs, which cannot be authenticated in any way, could be admissible in court. But then, military courts aren't usually concerned with justice.
