I always thought a more comparative witness system in ES would be awesome. Of course everyone hates that when you kill someone in the wilderness but still get a bounty for it, I think that, especially if you have killed someone, there should have to be witness(es) that run or call the guards in, or you could even have the opportunity to bribe or intimidate them to keep tight lipped. Reality at the time is that the law is only based on this witness evidence or possible clues left at the scene of the crime. I mean, if you are seen walking around with your sword out in the middle of the night in a city and there is a murder that night, even if it hasn't been seen by civilians/guards, anyone who has seen you walking around suspiciously like that may still suspect you of the crime, which is also where witness posters should be brought in, and the guards could arrest you on a murder charge that you may or may not be found guilty for. Search party's are another idea, so if you say killing a guard patrolling roads between two cities then a group of guards will be sent looking for him, and it depends on how well you have hidden the body to see if they find him.
