what i can't fathom...(spoilers)
this may be nitpicking a bit, but it makes no sense from a writer's standpoint for Jake Berman to think it's a good idea to shoot his partner right in front of his wife. i mean, yeah he had 'good guy' motives for doing it, but wouldn't a concerned, caring husband think "hey, maybe she's already seen enough people get shot to death while she's sitting next to them"...?
getting the blood of someone you care about splattered all over you (TWICE!) has got to have some kind of foreseeable negative effect on a person...right?
but this apparently got past both Jake and the screenwriter.
