not only Does the ending make the princesses comments about being on a diplomatic mission not make sense but the fact ( I always thought a bit strange ) that they let the pod with the droids on it escape saying it was a malfunction even more ridiculous. I always assumed it was more like a traffic stop situation where Vader surmised she would have the plans. they literally just chased them down from a battle looking for stolen plans and an escape pod leaves and these Nimrods just watch it go .
Still I have to love a movie where all the rebal scum die horrible deaths for a frivolous cause.
LONG LIVE THE EMPEROR !
I'd have to argue against the diplomatic mission part not making sense. I believe that Leia was making an excuse as a lie to that and Vader called her out on her BS.
