Skyrim isn't earth. Not sure what that example has to do with anything at all anyways other than switching blame to someone else.
What I'm trying to say is that the world the TES games are in is more or less more primitive world.
They are at war and they don't have the technology to take fingerprints etc.
We aren't even at war (ok, Murrika is awlays at war with someone) but still we have people running around killing and we don't say that is a reason why a governemnt is a bad government.
I hope you kind of get what I mean
