As a former Criminal Defense Attorney, I would agree that you probably don't want to be asking questions about the incident while it is pending before the Court. I am think legal grounds and leadership grounds here. The legal grounds have been touched on and very jursidiction to jursidiction. But the leadership grounds are pretty universal.
In Scouting, no matter the level, Cubs, Webelos, Boys, Venture, etc., we are working with children. During this process, we, in part expect respect and trust from our charges and their families. However, these must also be earned. We constantly talk with the boys and get to know them and their families. We are there as a resource for them. We sometimes are "parent in locus" in many outings and meetings. Sometimes, in times of need, these kids turn to us for advice, somebody to talk to and help. We give them advice, punish them for misbehaving and reward and recognize them for good deeds. Sometimes, we are the ones that the kids feel the most comfortable to talk with regarding problems, concerns, etc. If word gets out, that a Scout Leader knows about the activities of the Scouts that is accused of a crime, and Law Enforcement tries to get information from the Scout Leader about what the boys has said to him, and there is no privilege in the Scout Leader/Scout relationship, puts the Scout Leader in a bad situation. Generally, the State Laws say you need to tell Law Enforcement what you know. But now, you have breached the confindence with a Scout. He could have been looking for direction or help and made a decision based upon that or followed the advice of his parents or attorney in dealing with the Criminal Case. We want boys to come to us with their problems and if they think we will breach those confindences, they might not. I know this opens a whole can of worms, because what if they come to us because they are being vicimized or abused. Leaving that at the side for the moment, the boys need to trust us on a lot of things.
The boy in question here will need to face the consequences of his actions. It could be a juvenile disposition, it could be being denied an Eagle, it could be loosing other things, ie. sports or other school associate activities.
I don't think anybody here is saying throw the boy away, but a question on how an Eagle Scout should be preceived and how Scouting will look if they award this boy the highest honor in Scouting. Unfortunately, there are Eagle Scouts that get into trouble after they have been awarded their Eagle Scout, does that diminish the award? In my opinion, the award should focus on the boy and his actions and accomplishments. Most juvenile cases are resolved fairly quickly, unless it is a major felony. I say support the boy and be a resource for him and be there to help him through this. You don't have to condone his actions, but you can support the learning and rehabilitation that comes with the consequences of his actions. I would contact the parents and tell them that the grapevine says he maybe in trouble and what can you do to help him. It appears the decision on Eagle can be postponed, I would worry more about the boy than the award.
