Take it to the bank, my source is impeccable.
I think he still has the problem of Murtha never mentioning him by name in public.
No he doesn't. Murtha was blanketly passing judgement and condemning a specific squad of Marines, of which Justin was a member. The name of every Marine in the squad was known publicly, it wasn't necessary for Murtha to name each one individually, his words condemned them all.
Murtha is a slime ball and I truly hope that Sharratt has a cause of action against him and can prevail. I have read every USSC case related to defamation and I think the fact that Murtha never mentioned anyone by name is a problem. Murtha stating that a Marine squad committed murder does not identify Sharratt individually.
If this case goes forward, I can assure you that this fact will be a defense he presents.
