How could there have been criminal wrongdoing here?
If anything, it was criminal that the Boy Scout leaders didn't think about basic electrical concerns.
I was a Boy Scout and I'm glad I was. However, there was an "Electricity" merit badge (which I received).
They needed some very basic electricity knowledge. The leaders were responsible for their own deaths.
While all of us know who is to blame, the idea is that an ambulance-chaser will sue the "deep pockets", the taxpayer (via the Military), as usual, and if the finding is for $10 million, and they split on 'negligence' is even 80% for the Scout Leaders' fault, the 20% remaining is still $2 Million which will get the Lawyers in the neighborhood of $1 million for themselves (50% contingency fee), or even if the contingency "fee" is 30% plus expenses, they will still get $1 million of taxpayer money as a settlement, via the Army being only a conduit to reach deep pockets.
