I agree. Do you realize that if a boy had done that to a 12 year old girl, he would have been (quite rightly) charged with assault? If there's ever to be true equality for women, it should work both ways. What's sauce for the gander should now be sauce for the goose. I would insist that the girl receive (at the least), an out of school suspension. If my request was refused, I would dump the whole matter in my attorney's lap and let him file suit against both the girl and the school. Things happen but it's the school's responsibility to handle a problem like that fairly and that's not a fair resolution. It's an assault with sexual components and an in-school suspension doesn't cut it. Nobody should have their privates exposed by having their clothes yanked down in public. It's a physical assault and the girl can and will be arrested for it, should you decide to press charges. She'll be convicted, too so actually, an out of school suspension is getting off lightly.
