Does seeking justice really mean unforgiveness? I

See woman raped in college. Watch man who raped woman contact her 20 years later. Man confesses. Woman probes. Woman finds that man has not really accepted responsibility. Man is charged in court of law. Man pleads innocent. Woman receives letter from Christians criticizing her for pressing charges against man. Christians say woman should forgive.

I have one question in regard to that: What does forgiveness have to do with justice?

Man breaks law. Man should go the prison. If man wishes to act in a Christ-like manner, man accepts responsibility as well as punishment.

Why criticize Liz Seccuro for working with prosecutors who want to bring to justice a man who commits rape? There is not one place in the Bible, that I can find at least, that God says people who break men's laws on this Earth should not be held accountable for those wrongs by the society that make the laws.
