A more thorough explanation:

Parolee

A person who has been released from prison before their sentence is finished, but is still under supervision and must follow certain rules.

• John was a parolee after serving 5 years in prison for robbery.
• Samantha was granted parole after serving half of her sentence for drug possession.

These examples illustrate how a parolee is someone who has been released from prison before their sentence is finished, but is still under supervision and must follow certain rules. John and Samantha both served time in prison, but were released early on the condition that they follow specific guidelines and report to a parole officer. This is a way for the justice system to monitor their behavior and ensure they are not a threat to society.
