I understand your view Jack but for all sorts of reasons criminal proceedings fail. Most of those reasons don't have anything to do with whether the behavior was actually criminal, or even wrong. Also it might be months before the matter is dealt with in court. And all the person is free to come and go from the conference - the police aren't going to lock a person up for a week waiting for a court appearance. What the conf does with regard to dealing with the matter here is crucial - do they fail to act, sit on their hands and say "its up to the authorities" ...? How will that look if/when the authorities fail?
