Continuing my Morroblivion playthough...
When I confront this foul-mouthed Ordinator (http://www.uesp.net/wiki/Morrowind:Suryn_Athones%27_Slanders) with his slanders, making him attack me, the whole Justice Office joins in the attack (defending him, I presume, not caring who attacked first), which is not what is supposed to happen.
Needless to say, all Justice Office quickly PWN's me.
(These "Radiant AI" and "in Oblivion, people know how to pass though doors" thingies can, apparently, cause quite a lot of issues with Morrowind quests).
I removed him from the Temple faction and reloaded the save, but the Justice Office people still attacked me. They even did so after I removed him from the default Morrowind faction.

Attempting a solution, I not
Attempting a solution, I not only kicked Suryn out of the temple faction, but changed his class to Thief. Now the Justice Office helped me deal with him, instead of helping him.
Of course, that's still not ideal, since they really should stay neutral.
