The term 'Old West Outlaw Chasers' refers to a group of people who were responsible for tracking down and apprehending criminals in the American Old West. This group was commonly referred to as a POSSE, which is a five-letter word. POSSE members were typically volunteers from the local community who were deputized by a sheriff or marshal to help with law enforcement. The POSSE would often pursue outlaws across long distances, sometimes even crossing state lines, in order to bring them to justice.
