NPCs don't seem to really care if their prized diamond in their glass casing suddenly disappears. I'd like it if they started to care.
Here is what I think is the most simplest solution right now:
If, lets say, I steal 2 diamonds from some rich fellow's glass case. The fellow sees this, and thinks:
"Oh no, my two 2000c worth diamonds are missing!"
And proceeds to rush out and raise the alarm, which would trigger those large shutters, which should trap the player, and inform the enforcers.
This would make theft a more high-risk affair, and gives a reason to stop players from hogging everyone's' belongings whenever they can.
Maybe in the far future, there can be other investigators, either working for a division or private, who would investigate stolen cases that you may have caused. And how long a case is investigated for before it is closed is dictated by the social standing of who was robbed.
Maybe the punishment in this case would be a fine of what you had stolen, and a decrease of social credit.
