Did you ever see the movie Midnight Run?

Good movie, with DeNiro and Joe Pantoliano from The Sopranos as a bail bondsman

The bail bondsmen hires someone to find the fugitive. If he is found and returned to the jurisdiction of the court, the bondsman gets his money back.

The fact is, though, that most people do not jump bail, so the occasional loss that the bondsman suffers is more than offset by the profits.

Also, the bail bondsman is under no legal requirement to post bail for someone.

If he considers a person to be a "flight risk", he doesn't have to deal with him.
