Japanese Teachers

A teacher at a secondary school resigned yesterday after it was made clear that he was sexually harassing his students.
During swimming classes, the teacher would write things like "What is your bust size?", "I want to have sex with you", "tell me the name of the boy you like" on a golf ball and throw it in the pool.
After forcing the students to swim down to collect the balls, the teacher then made the girls write down their answers to his perverted questions and read them out aloud.

So what happened to that teacher? Nothing - he gets away scott free just by handing in his resignation. Unfortunately this is not the only case of sexual harassment in schools and can be regularly seen in the news over here.

Are there cases of harassment (sexual or otherwise) by teachers in your region?
I remember a teacher back in primary school who kept using the F word to encourage kids not to use it. She would bring the kid to the front of the class and say "Why the F*** do you keep f**king swearing?" Seemed to work as it normally left kids trembling after the experience.
