Her father should have raped her..i think it could be a little fair.

He still can.  :o

The thing is, not only can he do it, he won't even get caught for it.

Double jeopardy is a procedural defence that forbids a defendant from being tried again on the same (or similar) charges following a legitimate acquittal or conviction. In common law countries, a defendant may enter a peremptory plea of autrefois acquit or autrefois convict (autrefois means "previously" in French), meaning the defendant has been acquitted or convicted of the same offence.[1]

waiting for the lawyer to be bro to input his advice.

An instance of rape in 2012 would be a separate charge from an instance of rape in 2001. Double jeopardy would not work here. Might go a long way to winning a trial though "she already lied about this shit once", but physical evidence could be damning regardless of testimony. If he like used a condom, and cleaned her up well enough afterwards he could probably get away with it if it came down to his word vs her word.
