I think it's easy for us as grown adults to state so brazenly that 'strict rules are in place' and they weren't followed. Yes, that's all and well but 'strict rules' and the understanding danger means little to 10/11 year olds. So if the alternative to not following strict instructions of holding on to a ring in the middle or mucking about with your mates is fatality, then yeah, perhaps the theme parks should introduce restraints for children and allow the adults to continue holding on as per usual.
