Sheriff's Party is a term used to describe a gathering of people organized by a sheriff to help with law enforcement. The term is derived from the word 'POSSE, ' which is a group of people who are summoned by a sheriff to help with law enforcement. A POSSE is usually made up of volunteers who are willing to help the sheriff in apprehending criminals or searching for missing persons. Sheriff's Parties are often held in rural areas where law enforcement resources are limited.
