Okay...mom of two scouts here....
He put children in danger of drowning on not one, but two occasions. He took a closed trail, AT PHILMONT, with younger scouts. This man is not qualified to lead a scout troop. With a troop of only 25 boys, he will have an undue amount of influence, especially with mom being the committee chair. Anyone who breaks the safety rules, and endangers children does not need to be in charge of the troop. He has no business being scoutmaster. NONE, no if, ands, or buts....
A scoutmaster has to put the kids safety first. He has to work well with others, that is what being scoutmaster is all about. I would ask several of the boys in the troop how they feel as well. If he has no rapport with the boys, he will be useless. The BSA has all those annoying rules for very good reason. Troops that follow them are safe, effective and good for the boys. Leaders who don't think the rules apply will poison the troop.
You don't become a scout leader for your resume, or because your mom thinks you should; you become a scout leader because you are passionate about scouting, or because you have children who are scouts. From what I've seen there are two, maybe three types of kids that become Eagle Scouts: those that love scouting, those that love achieving, and those that are forced by parents. My guess is this guy did the minimum required to become Eagle, only because he had no other choice.
I'd take my boys, my training, and my skills to another troop if this man becomes scoutmaster.
