Do you think they deserved to die?!
There was a moment in the trial that didn't make any sense to me. It's when the prosecutor asks Carl 'Do you think they deserved to die?' and Carl admits he does. The film portrays this as a big victory for the prosecution - the music, the victorious grin on prosecutors face, Carls lawyer looks devastated...
But from judicial point of view it doesn't make any sense. Sure, usually it's a strong point to have the defendant admit he thought the victim deserved to die. But that's only when he denies killing him/her. This question (or the answer to be precise) establishes a motive. In Carl's case, nobody in the world would doubt his motive and nobody could have expected a different answer to that question from him.
So - the prosecutor achieved only one thing with this question - he showed us that the writers of this movie know nothing about murder trials.
