Some people here sure get personal as IF they have a vested interest in the issue.
As for this case, I can offer my own life experience. When I was a senior in high school I was still 15 until my birthday in September. My girl friend was 18. The notion that she was guilty of some crime requiring 10 years in jail is crazy.
If the sex was consensual, 10 years is wacky. It's a bad law that requires immediate attention. There just is no moral equivalence between an 18 year old having relations with a girl who is almost 16 and a twenty something having sex with a 13 year old.
There needs to be some judgment involved here.
