It's difficult to tell what was going on by the logs, but just reading through, it seems like HalfdanWhiteShirt was probably the reason things began to get out of hand.
Looks like it started off with poll-abuse; a kick poll against Heisenberg just to push buttons.
He appears to be a very new player with no alts and no prior ban history.
This alone will be a short ban on Halfdan, two hours, to serve as a warning and flag other admins in the ban logs if something is to happen again.
Posting the original confrontation. Note the differences in time where I've deleted endless kill logs:

There was a bunch of back and forth for awhile when Heisenberg went off a few of you in there, apparently for a teamwound report.
It's really tough to tell just what all was going on, if he was being trolled (wouldn't surprise me either), but attacking your own shieldwall in DTV is a surefire no.
As he attacked two of you, I'll say 12 hours for each person, 24 in total.
If people are trolling you, take screenshots. Don't teamkill them.
This hurts the entire team, the majority of whom are minding their own business.
