Stupidity: There is no logical reason for a bookkeeper to be present at the liquor deal on the Canadian border and even less of a reason for him to bring the primary ledger with him. This is compounded by the fact this is merely a secondary bookkeeper and the main bookkeeper is subsequently subpoenaed by the district attorney.

Directed by: Brian De Palma
Starring: Robert De Niro, Kevin Costner, Sean Connery, Andy Garcia
Continuity mistake: When Ness is "escorting" Nitti off the roof of the courthouse, watch the proximity of the two to the rooftop door. When the camera cuts from the edge of the roof to Nitti and Ness and then back to the edge of the roof, you can see that they went from close to the rooftop door to really far away from it.
Jimmy Malone: He pulls a knife, you pull a gun. He sends one of yours to the hospital, you send one of his to the morgue. That's the Chicago way!
Trivia: As the stroller is going down the stairs in the train station it is a reference to the staircase scene in "Battleship Potemkin" in which a stroller similarly falls down a flight of steps while the horrified mother looks on.
Question: In the scene where Malone is shot by Nitti, he crawls to a room and when Ness comes in he finally gets Ness to see the paper about the man coming into the train station. If that information was so vital why was he just roaming around his apartment instead of going to Ness to show him?
Answer: Ness was coming to Malone's apartment to discuss the information with him there, Nitti and his men just got there first.
