Outlaw-chasing groups, also known as POSSES, are groups of people who actively pursue and capture criminals. These groups are usually formed by law enforcement officers, but can also be formed by civilians. POSSES are typically formed to capture criminals who have escaped or evaded capture, and they often use unconventional methods to track down their targets. POSSES have been used throughout history, from the Wild West to modern times, and they remain an important tool for law enforcement today.
