I, too think it's sad we need a law.
I do not understand why people are unwilling or incapable of imagining themselves in the position of the person with the least power and behaving according to how they would want to be treated if it were them.
So in this case, the kid has the least power. So that assistant told immediately, but he didn't follow up (read he is a full time assistant there now). If he was that child, wouldn't he have wanted the one person who saw it to help him in every possible way? Not just the chain of command, but above and beyond?
Even outside of sexual abuse, this exercise has merit. Look at it from someone else's perspective, what is right becomes much clearer.
