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!
Elliot Ness: I have one more thing to say. I know that many of you take a drink. What you've done before today is not my concern. But now we must be pure and I want you to stop. It's not a question of whether or not it's a harmless drink, it may very well be, but it's against the law, gentlemen, and as we are going to enforce the law, we must do first by example.
Answer: It's about 50% truth and 50% fiction. Ness, Al Capone, and Frank Nitty are real, of course, but the characters played by Connery, Garcia, and Smith are fictional. Ness started out with 50 candidates for his 'Untouchables' force. This was whittled down to 15 finalists and from that he selected 9 agents (none of which has the same name as the characters played by Connery, Garcia, and Smith). It's true that Capone was convicted for tax evasion. He was sentenced to 11 years in prison, but received an early release because he was in the last stages of syphilis. He died shortly after being released from prison.

Capone lived for 8 years upon his release from prison. The 8 years being slightly longer than the actual prison time he served, which was just over 7 years. He died, having the mental capabilities of a 12-year-old.
