Most people that are told to come along or else generally just pull the power, or they run away at their first chance. Most crimes are done by alts, so I'm going to go and make a bet they wouldn't give a flying shit if you killed them or not.
I'm against this tying up business. What's stopping people from knocking out and shackling a innocent newb and just fuck around with him? What's stopping people with a rope from tying people up over and over again, this is ridiculous. If you want to do this, just make it so we can pick up unconscious bodies. Yeah, they will run away again but it will be easier then us saying "or else" which will not work. Also, what's stopping the person from just hearthing when they are on trial? Or being carried for that matter. This is poorly thought out.
