Even in cases where the law states that it's illegal for a 18yo to have sex with a 17yo, it's still up to the prosecutor to be sane about it. That doesn't always happen.<p>When the girl is pregnant, she still has to give up the father for them to know who to prosecute (traditionally the boy is prosecuted in these cases; <i>sometimes</i> they go for the girl if she is the older one, but if she is pregnant they may view her as the 'victim'). I guess she may give that information up when declaring who the father is to the hospital though, so I don't know. Maybe it just depends on how vindictive the parents are.
