Mmm. As I ruminate on this, I think fistful is correct.
It is clear a film this long could not have ended up there by accident - after all, it's all of six seconds!. It is absolutely clear this evil woman was attempting to expose children to her horrible, perverse habits - in the same way as pedophiles expose small children to pornography in order to 'groom' them as potential victims. No doubt, this was her plan.
As such, this woman must be some form of pedophile sex-predator. Society must not tolerate such men and women as the custodians of our precious children. The authorities must act at once. First of all, and whatever the outcome of the proceedings to follow, she must be immediately and summarily fired, and blacklisted from any future work in an educational institution. Second, a judicial warrant to search her home must be found, to help prove the obvious child abuse charged that must immediately be filed, and to uncover further, horrible crimes. It would be best to acquire a no-knock warrant - lest this horrible woman remove additional evidence of her crime from the premises (not that additional evidence is required) when she hears the police knock. A tactical-team of the county's finest troopers should be sent in to deal with this dangerous predator - after all, this is what police gets their surplus M113 for, right? I am sure I speak for all of us upstanding citizens saying that nobody minds if this predator gets tazed a couple of times during arrest, right?
After the arrest is carried out, it is our moral duty to charge the lady with the proper sexual crime charges, with one count per every DVD distributed. And after she serves out her sentence - assuming she doesn't die in prison, of course - she must be barred from living within, oh, say, a mile or two from a school or kindergarten. By this time, the children whose minds she so irreparably damaged will surely have children of their own, and maybe even little innocent grandchildren - and they would not want this predator who so damaged their souls to be near the schools and playgrounds where their children play!
