Thank you for the info. This is disturbing. Hopefully this will be "fixed" and killing a man on the side of the road is not resolved in my being arrested 8 towns over. Like they say "should a tree fall in the woods with no one to hear it does it make a sound?" (if you kill a peasant in the wilderness will the guards know?)
They have said they are really working to get rid of the guards "hive mind" for lack of a better phrase.
I hope it was only a small bug, because no other previewer had that issue.
I mean, if you read the other PAX Gameplay reviews, they are riddled with "so I killed them, then them, and them too."
But he seems to have been the only one caught.
So, while it does raise concerns, it looks like more of a bug.
Here's hoping.
