Since this thread started with a disparaging comment about the scoutmasters who died at the jamboree, and having known a couple of those men, I have read through all of the posts. Lots about the merits or demerits of the scoute. I would suspect they are only as good or as bad as the adults who lead them. They are undoubtedly religious since many of them are sponsored by churches that will want to influence the boys, but there are others that are probably less religous.
When they decided that gays and athiests couldn't be part of their organizations, I decided I wouldn't support them anymore.
But as to the men who died, they did believe in scouting and worked hard in it. At least the one I knew best would not have been careless, had a healthy respect for electricity and had worked around it and with it most of his adult life. In this case he probably came to the assistance of someone who asked for his help and probably expected the professionals who were there knew what they were doing.
He was a very fine person and his death is a tragic loss to family and friends.
