Digging to the history of a crime, if the investigator is really good, if the law will proceed the case and really wants to prove who is the real suspect and victim, it would be open. However, I am not good at this, so I cannot explain further. If you ask me if a woman,accusing a man of raping her, after 30 years she spoke up, regardless if it is true or not, I will be in big doubt. Why? Why are you telling just now? Why are you speaking now that it has been 30 years. Does your reputation before doesn't matter? Does it not affect your decision in life? Did you live normally for 30 years and after 30 years your life sucks, you remember the man who rape you and starts to accuse him? I will be in big doubt. If the accusation is false and proven by the law she could be in penalty or in jail.
