As of now the developers have indicated that the maximum jail sentence is 45 real life minutes. This to me is too short to seriously discourage trolls from ruining the realism of the game by randomly killing other players. Since the real life penalty for murder or other major crimes is either life sentence or death there should be some more serious penalty in the game in order to discourage trolling and to increase the risk of committing major crimes.
In my opinion the penalty for murder should be at least 2-3 real life hours. If the developers still insist on keeping it at 45 minutes, I suggest enabling private servers to adjust this time as a default setting or through mayor/government decision.
