Moral

So the moral of the story is; if you're gonna rape somebody, make sure they have a history of lying - do your homework first

And bribe everyone.

How sure can you be that he's guilty?

I say he;s innocent till I see proof to the contrary.

Or maybe: if you're going to pretend to be raped, make sure you're not already known to be a liar.

Hard to tell really, could be any of these two morals.
