The Pelican Brief - looking for a spoiler!

Julia Roberts is supposed to be meeting with an FBI agent. The agent has been killed and replaced by the assassin. Who is it that shoots the assassin at the amusement park?

It’s a 20 year old movie so you can probably skip spoiler tags!

The pelican wears boxers.

In the book, it was federal agents shadowing everyone involved, IIRC. I believe it was the same in the film.

Turns out pelicans don’t wear briefs. Mind --> Blown.
