any adult having sexual contact with kids should be executed
16-17 year old guys are not "kids."
16-17 year old people are young men and women...in many parts of the world they lead families....years ago, in this country they were considered no longer children.
I more than understand your concern, but I have worked with young men 13-18 for many years in the juvenile justice system and I can ASSURE you that the older ones are not children by any figment of anyones imagination.
I further understand that rules concerning such actions in a school environment should have zero tolerance and in that respect she is, of course guilty. However, charge her with the correct offense, not seduction....she seduced noone but is guilty of violating her responsibilities as a teacher and state employee.....PERIOD.
