What about statute of limitations laws? Should we do away with all of them? He! Let's go allllllllllll the way back and reinstate every ridiculous law there ever was.  Laws change. They aren't written stone and many should never have been written in the first place. Remember abolition? How many people were falsely turned into criminals and served long sentences as a result of that enormous idiocy? 
Try studying the development of law sometime. You really need to.
