I think the teens were "legal", but the doesn't the law "protect" them (students) from people in authority (teachers, administration, etc.)?
yes and that is what I don't agree with
Teacher A has sex with 18 year old student = illegal
Teacher B has sex with same 18 year old student = not illegal
how you may ask, well Teacher A taught student in May in high school and Teacher B taught student in September in college
or simply Teacher A teaches at students high school but doesn't even teach the student and Teacher B teaches at different high school
I just think it is stupid to criminalize two consenting adults having sex (exceptions for prostitution and penal institutions)
