Why wasnt her teacher arrested

...has no idea why not....after her run around the barn.

What I dont get is how that sleazbag teacher knew he would be able to get away with the rape, how did he know she would not tell anyone and how did he know the witness would be too traumatized to report it? he just totally lucked out.

Plus if he was that kind of a person it makes me wonder how many OTHER victims he had.

To be honest when a rape victim does not report their rape I end up feeling a degree of hate for the victim. I know that sounds heartless BUT to me it is the ultimate act of selfishness to be a rape victim and NOT report it for this reason: The rapist will almost certainly seek more victims, and I consider anyone who does NOT report him to be partially responsible for that. If the person had been reported on their previous victim (unless you are the very first) than you would not have been raped. So every victim after he rapes you is morally partly your fault if you do not report. I hold the main character of this movie responsible for any other rapes that occurred after her rape.

The statute of limitations in Minnesota for rape may have already expired by the time he was summoned to court. Because she never told for the longest time, he may have got off scot-free because of it.

Uh, a simple googling will tell you that the age of consent still is 16 in MN, like in most states (though as of now teachers can't touch kids under 18). But it really doesn't make sense that the teacher is supposed to be some kind of victim... Teacher is banging your daughter: even if you have some backwards ideas you might spank her, but you're going drag him behind your pickup and burn the corpse

Your reasoning makes no sense. Obviously this story is made up, but it's certainly a composite of things that have occurred in real life. A teacher could never rape a student because it's "not allowed" and "not consensual"? There is a difference between forcible and statutory rape, even if the forcible rape is against a minor. Why would ANYONE think they can get away with rape? Only because it happens all the time, victims are shamed and humiliated into silence, and conviction rates are startlingly low, and when assailants are convicted, sentences are often very mild and do not reflect the gravity of the crime at all--like a suspended sentence, time served--fitting punishment for a brutally violent crime that will likely alter the victim's life, sense of self and personal safety, etc. for the rest of her life? No, it's really not. A year or two in prison is not enough, either.
Bottom one is, this may be a movie teaches have raped students in real life, not just as "consensual" but still illegal sexual relationship with a student--I mean violent attacks. So often, victims are up against so much more than the assailants that the thought of having to deal with it is almost as horrifying as the rape itself. The way victims are treated by community is another thing--some are harassed or blamed for their own assaults. Some cultures prefer to "work it out" between the families involved, which basically always means making the victim "make up" with her attacker, agree to forgive him and pretend that it's all some silly misunderstanding.

The sky is blue

Some girls dont speak up about their rape attack because they're concern about their reputation and others because maybe they participated in a group party that involved alcohol, drugs and weed/marijuana so they wont be able to claim to be a victim and depression/alcoholism will not help ease the pain.
