I just watched the 60 minute show on "drinking in the house." The gist of the story is a parent decided to host the after prom party. The parent did not supply the alcohol but knew it was present. The parent did take all the keys and did not allow anyone to leave once they were there. This parent was arrested a one week later.
Moral of the story, if it is against the law, IT IS AGAINST THE LAW! The scout is not living the "Scout Law."
