First, he's accusing people of a federal crime, so I'm sure he has a lot of evidence to back up his assertion (gee, I'm really really super-duper sure of it). Second, does anyone really believe that embarrassing records, that are being destroyed illegally, would just be put into a trash can and left? And third, "a few days later" he saw the illegally-discarded files in a trash can, and didn't save them?!?!?! Again, I'm super-duper sure he has evidence to support this, because the Lt. Col. has admitted to committing a crime if this is true, by not retrieving the allegedly-discarded records!

Perhaps that is just what he claimed to CBS that he did when he gave them the forged files.
In their minds they'd be protecting him from charges of stealing documents by not revealing him as the source.
