The boy is almost certainly "innocent" in the classical sense.
What if he was in 12th grade and was making clowning around type sexual advances to another 12th grader? Would this really be wrong? No, of course not. It's a normal part of co-ed life for post-pubescent males to make advances to post-pubescent females. There are private schools for parents who don't want that. In many states, government funding follows the student around, so it would be free or nearly free to the parents.
Isn't it true that children tattle tale about each other to the teacher? Yes, of course. The younger they are, the more they do it. Tattling is part of learning not to do bad things themselves. Teachers and school administrators have special post-graduate study and teaching internships that's supposed to prepare them for the real world.
If I were the father of that boy, I'd raise holy hell about it at the school board meeting, threaten to sue, and hope some scumbag lawyer showed up at my doorsteps eager to do the deed.
Almost forgot: OP makes a good point. Some countries have laws against "defamation of the state" which makes the fictitious entity the state equivalent to a human being (as does the official US view on corporate personhood). These scattered court rulings (common law) could easily form the basis for legislation about some supposed "defamation of women" (as a "corporate entity" or "class" being violated under the 14th Amendment).

I am not her man. She can't stand the thought of me touching her. She's dripping with other men's semen. She is ashamed to be seen with me. She never misses an opportunity to disrespect me. Everything I do is wrong. I am the problem. She got what she wanted from me. She says "I hate you so much I could kill you." Going away forever will make her happy again. So I'm leaving her to her pumped-and-dumped lifestyle and leaving her bastard child fatherless. I'd be better off with no woman at all than wasting another second thinking about her. I learned from my mistakes and the next relationship will be done with planning for my happiness.
BTW guys, at the very moment of this post, my recent b1tch is over at her boss' house making herself available to him yet again. They too have a stormy affair.
