I agree.
There is no justification, ever, for adults having sex with a minor
And before people jump on both you and me, we are NOT talking about the case of an 18 yr old and a 17 yr old who do this (even though I would say we would not be in favor of them doing that at that age and being unmarried). we are talking about adults and especially adults in positions of trust and authority over said children, who are supposed to be acting in loco parentis or otherwise shouldn’t be bugging a kid that isn’t their own in the first place.
This may also apply:
§21-1111 8. Where the victim is at least sixteen (16) years of age and is less than twenty (20) years of age and is a student, or under the legal custody or supervision of any public or private elementary or secondary school, junior high or high school, or public vocational school, and engages in sexual intercourse with a person who is eighteen (18) years of age or older and is an employee of the same school system.
