Not to indicate which way I'm leaning right now, but that statement is nonsense. His injuries could be to lower extremities, not affecting his ability to type. Things could have gotten worse, pain wise, and they might have medicated him causing him to conk out. There are other possibilities as well.
It would be interesting and useful to know if the time stamp on the email is before or after the time stamp on the thread.
'Nonsense', I don't think so, but we will find out. Tell me El Gato, if you were a new poster, or a lurker for a while and you were injured in the war, would you think to have a thread posted on FR about your injury? Would be the furthest thing from my mind. As I said before, I am skeptical, and if I am wrong, I apologize to Captain Mike Pierce.
"Not to indicate which way I'm leaning right now"
Just for the record, I lean 'right' ;-)
My prayers are with our Military, each and every day.
