Two questions - spoilers
I missed the first few minutes of the film, I came in when Malik was putting the money in his shoe. What happened before that? Did they explain why he was arrested?
At the end when he is in solitary confinement and everyone starts killing each other, what was that all about? Was he suppose to kill both the corsican guy's boss (the italian guy) and spared him which resulted in guys loyal to the italian guy going against the corsican guy's people? If so, why did they spare the corsican guy? Why were the arabs involved in the fighting, they didn't have anything to do with it?
