This thread comes across as if all accusations made against adults supervising kids are false.
While it is wise that you all protect yourself from false claims (look at Dale Akiki for proof on why that is necessary), I would like to point out that it really does happen.
I can tell you from being on the receiving end from my jr high counselor. I was able to stop him before it became physical, but from what I learned later others weren’t as fortunate. From my experience with his actions behind closed doors, I can tell you their claims are true.
