Bobbing around on the water in the dark with all the other boats is certainly a challenge.
We were out w/ friends on Lake Tapps a few yrs ago for their 4th fireworks show. Us and ~200 other boats of all sizes. What a mess. I can only imagine how many of those boaters had been, uh, enjoying some adult beverages. Thankfully everyone seemed congnizant of the close quarters and we made it back w/out issue, but it was interesting.
I have spent years around law enforcement and the hardest thing to teach these young officers is that they are absolutely required to intervene when another officer is making a mistake...
It's called leadership. IME the younger "bucks" are usually full of vinegar as you stated. In general, I see the leadership quality in those that come from the armed forces, but not from those that come from, say, a university/civilian life, where being accepted by a group is a social requirement.
This incident is a sad situation all around.
