Prisoner rights refer to the legal protections and entitlements that individuals retain even while incarcerated. These rights include access to basic necessities such as food, water, and medical care, as well as the right to communicate with the outside world, including family and legal representatives. Additionally, prisoners have the right to be free from cruel and unusual punishment, as outlined in the Eighth Amendment of the U.S. Constitution. They are also entitled to due process in disciplinary actions and protection from discrimination based on race, gender, or religion, ensuring fair treatment within the criminal justice system.
