The logs show a single head-shot kill, no repeated teamkilling & no additional teamkills (it sounds like the battle was just about over).
It's hard to determine intent from that, although chat seems a little suspicious with the carelessness of it happening.
In either case though this is one of those single event "your word against mine" scenarios, and admins were on with no action being taken, so I'm going to let it be with no action being taken.
Tim you might be getting away with one here, so please be mindful of your teamkills in the future if you want to avoid ban-time.
