Who advocated for supervising probationers and revoking probation if the accused returned to crime?

The advocacy for supervising probationers and revoking probation upon reoffending is closely associated with figures in the criminal justice reform movement, particularly in the late 20th century. Notable proponents include John Augustus, who is often referred to as the father of probation, and more contemporary voices in criminal justice reform who emphasize accountability and rehabilitation. These advocates stress the importance of monitoring probationers to reduce recidivism and ensure public safety.
