News stories about female high school teachers having sex with male students are a dime a dozen today. Do some Google searching and you will find literally hundreds of them. They rarely do any jail time; generally an exit from teaching and some kind of probation is the most that happens. The Mary Kay LeTourneau case is not really an exception to the rule, because she went further than most of them by having a student's baby and eloping with him.
Back to the case under discussion. If this woman had sex with a student, she should never teach again. If she did drugs with a student, she should go to jail. I was a hormone-driven teenage boy once, but I think I would have resisted this particular individual. PJ-Comix should really try interacting with a better class of woman ;-)
The whole thing is a salutary lesson from the public school system. I sympathize with the parents who have contributed to this thread.
