If the woman wants to kill the baby, she has obligation to report the crime to police. How else will the offender be prosecuted?
If the woman wants to kill the baby is lying about being a rape victim, she is almost certain to drag an innocent man into it, or use it to settle old scores. Even if she says she didn’t know the rapist and describes a generic stranger, some poor schlub will wind up arrested and charged.
Ask the Lena Dunham republican club guy “rapist”. Ask the Duke Lacrosse team.
This is a bad idea. Make it illegal, but these half assed measures will send innocent men to prison and the woman can lie just as easy to a cop as to a doctor.
