The real question is why do states have a statute of limitations on a crime that's sometimes a lot worse than murder and in the best cases, only slightly less bad? Yes, a statute of limitations is incredibly useful for petty crimes like stealing and other small things like that. We're talking here about rape and sexual assault though. As far as I can see, this is still a reflection on how poorly our societies treat women, even in the west. Perhaps the fact that the men in charge don't want to acknowledge the horror of rape? Women, however, are not the only ones getting raped. I truly cannot fathom the reason for this horrific limitation on justice, and I think if men being raped was more of a problem (outside prisons and jails where the authorities generally refuse to accept it happens) we would have no such limitations on rape or sexual assault.
