Why was Nicky Santoro (Joe Pesci) banned from all casinos?
Halfway through the film, it was mentioned that Nicky Santoro was banned from all casinos in Las Vegas, but on what grounds was it exactly? Was he misbehaving and being rude too badly and were they right to ban him like that? Did he not have anything to say in his defense or?
Also, when he stabbed that guy with a pen in a bar over a petty argument, how come none of the witnesses reported him for murder, at least those from a far, given how it was reasonably broad daylight and someone could maybe have anonymously taken a photo and gone to the police?
