Actually, they did, though they did it under court order.
I read hundreds of pages of the documentation posted online by a newspaper. It included a specific situation with an adult leader I knew decades ago a Cub Scout, a leader who was removed with no public explanation (at least none that I knew about as a boy; maybe the adults knew).
And then, there was an E-4 chaplain’s assistant working as a Scout Leader here at Fort Leonard Wood decades ago who got removed from Scouting, and later on ended up having to register as a sex offender due to subsequent civilian criminal convictions.
To say I got angry after reading the Scouting files is a gross understatement.
The Scouts did the right thing to remove these people from contact with young boys — including me.
To do anything else would have been a gross dereliction of duty.
So did I. In my case, I came across the records of 3 local council scout executives, who I either knew or had met, who had to act upon the files and expel the offenders.
