When someone has committed crimes, don't provide RRR services to them. Should be simple to implement. Do a check for crime flag. When it's above 1 or 2 or so, don't trigger the service. That way there won't be the audacity of criminals waiting for weakened ships to appear, destroying them and then repairing their own ship at the station. Eventually this would be the system anyway. Even if Crusader Security comes back at some point, it still needs to be a part of the system to not offer services to them.
