It's Not Hard to Understand
Soze thought he could get off the pier before the cops got there. He couldn't... didn't.
He had to use one of his old aliases to cover his tracks. He used his power and influence to get a meaningless charge that he has no intention of serving as Verbal Kint.
He will be out of the country by sundown.
What people have to remember is that he didn't yet know that a Hungarian survived the boat/pier explosion.
Yes, he talks his way out of helping agent Kujan through testifying, but he simply gets lucky in leaving before the drawing can be completed and faxed over to the police station.
A few more minutes and he was toast.
I love this film.
It is truly one of the best ever and McQuarrie truly earned that screenplay Oscar.
Having said this, I hate all the overanalyzing by fans and especially critics about the whole Kaiser Soze thing.
Yes, there is a Kaiser Soze.
He mixed in truth, half-truths and lies to what he told Kujan. Mostly, he just changed names. I believe the events were all real. For example, the whole thing with Redfoot happened. It's just that the guys name wasn't really Redfoot.
The most important thing to remember is that Kaiser Soze is real. It is Verbal Kint that is not.
"You think you can catch Keyser Soze? You think a guy like that comes this close to getting caught and sticks his head out? If he comes up for anything, it'll be to get rid of me. After that, my guess is you'll never hear from him again." - Verbal Kint to Dave Kujan
