Duane Chapman, also known as Dog the Bounty Hunter, is an American television personality, bounty hunter, and former bail bondsman.

A bounty hunter is a private agent working for a bail bondsman who captures fugitives or criminals for a commission or bounty. The occupation, officially known as a bail enforcement agent or fugitive recovery agent, has traditionally operated outside the legal constraints that govern police officers and other agents of the state. This is because a bail agreement between a defendant and a bail bondsman is essentially a civil contract that is incumbent upon the bondsman to enforce. Since they are not police officers, bounty hunters are exposed to legal liabilities from which agents of the state are protected as these immunities enable police to perform their functions effectively without fear of lawsuits. Everyday citizens approached by a bounty hunter are neither required to answer their questions nor allowed to be detained. Bounty hunters are typically independent contractors paid a commission of the total bail amount that is owed by the fugitive; they provide their own professional liability insurance and only get paid if they are able to find the "skip" and bring them in.
