-It could happen to any organization that doesn't run background checks on their volunteers.-
I'm just surprised we haven't heard about more of this, as chaos typically attracts the criminal element.
And it's unfortunately happening in churches. In the last two churches where I've attended, newcomers aren't allowed to work with children until they've attended at least a year. Then they must sign a criminal background investigation check before they're allowed near the kids. In our day, this is as it should be.
