I hope he gets off for the murder but gets busted smuggling or something for Freddy. SIN, really?
It was 'Sin' on one hand, 'Bad' on the other. i.e Sinbad, his nickname in there. Not any less dumb, but you know...
I think you can justify Naz's behaviour as a combination of it being a by-product of being in prison, his lack of faith in the justice system and being a Muslim, or what kind of a person he actually is, but do agree that the constraints of this being a mini-series means that it isn't as fleshed out as you would of liked.
