Question: How did Danny not get charged for taking hostages? He is even reinstated back into the police force.
Question: Why did Kevin Spacey shoot Samuel L Jackson? I know he wanted to fake his death, but he could've actually died. He could've just shot him with a blank. Also, did Samuel L Jackson know he was about to get shot?
Chosen answer: It's unlikely in the extreme that Kevin Spacey would have a blank round on him. He had to actually shoot him so he'd bleed and appear dead. Remember, both characters were improvising.
Question: The ending apparently had to be reshot, because the original ending leaked out. What was this original ending?
Answer: The original ending features a huge shoot-em-up, involving more than 150 cops, but it was changed to a shoot-em-up on a much smaller scale that involves only Kevin Spacey, Samuel L. Jackson and Ron Rifkin.
Question: When Frost attempts suicide, Beck shoots him in the shoulder to disarm him... why? He could have easily killed Frost (or Danny and Chris, who were several feet behind Frost).
Chosen answer: Beck wants Frost to stand trial and suffer for his crimes. Realistically a trained officer would never do this not only for the reasons stated but also because police officers are trained to shoot to kill, not to wound.
Question: I think Nathan is played by Paul Guilfoyle, however, after checking and double-checking I can't see Nathan on the end credits. Am I right, and does anybody know why he wasn't credited?
Answer: According to IMDB.com, Paul Guilfoyle did play Nathan, though he wasn't credited for the role.
Answer: Given the department-wide conspiracy he uncovered it's clear the authorities were unwilling to prosecute him.
