Prisoners are individuals who have been convicted of crimes and are serving time in a correctional facility, commonly known as a prison. They may have committed various offenses, ranging from minor infractions to serious felonies. The primary purpose of imprisonment is to serve justice, deter crime, and rehabilitate offenders. Prisoners live under strict rules and regulations, with limited freedom compared to the general public. They typically participate in programs aimed at education, vocational training, and therapy to help them reintegrate into society upon release. The conditions and treatment of prisoners can vary significantly between different correctional systems.
