I've read a couple of posts also complaining that the thieves in the Riften can't be killed and was wondering have anyone actually figured out why?
I'm playing a classic sword and board warrior goody-two-shoes... My impression that I got from talking to other NPC's is how everyone fears the guild and how horrible they are. So the first thing that popped in my mind was to remove the scum and off I went. I can kill all of them fairly easily only for them to drop to one knee... recuperate... and go back at it.
For this character I'm not interested in sneaking, stealing or pick-pocketing (for a re-roll hell yeah).
