Prison systems are institutions designed to detain individuals who have been convicted of crimes. They serve various purposes, including punishment, rehabilitation, and deterrence. Prisons can vary in security levels, ranging from minimum to maximum security, depending on the nature of the offenses committed by the inmates. In addition to housing inmates, prison systems often provide programs aimed at reducing recidivism, such as education and vocational training. These initiatives are intended to help individuals reintegrate into society successfully after their release, ultimately contributing to public safety and reducing crime rates.
