Well, it’s based on a book, so I guess the plot was already written.
I mean, rape cases are notoriously hard to win. The premise of the story is that Kate is a brilliant prosecutor, and basically doesn’t lose.
But, she does lose. In the book, it details how she lost a low profile domestic abuse husband/wife case - even though the husband was guilty.
And in the book, it even outlines why - all the defence has to do is a). be more persuasive, and b). plant a seed of doubt in the mind of the jury. Once that sees of doubt is there, it’s game over.
And it’s so, so simple to do that in a rape case - ‘he said’, ‘she said’, and there are so very rarely any witness. If the jury can’t be convinced beyond reasonable doubt, the rapist can’t be convicted.
So while Kate might have a good rack record of prosecuting rapists, it’s never going to be infallible - and someone as clever as she is, would surely know a jury would believe an MP who’s best friends with the Prime Minister, over some 20-something who sleeps with her boss.
Wouldn’t she have been wiser to give the case to someone else, and then appear as a credible witness herself - with the gravitas of being an Oxford graduate, respected barrister with 20-odd years experience, who was raped in virtually identical circumstances - James, on the move, in an adrenaline-filled situation, who rapes the woman who crosses his path while standing, while saying the exact same misogynistic line?
