This ARTICLE is concerned with the possible impact of recent technological innovations on the traditional probation officer's role. We identify several technological breakthroughs such as computerization, evaluate them and reflect on the implications of these changes for the probation department. We shall attempt to demonstrate how the hi-technology revolution would reshape both the role of the probation officer and the nature of probation supervision. Specifically, we will show that these changes have been most dramatic in the areas related to the officer's law enforcement functions. In contrast, there have been few technological applications in the field of rehabilitation. We contend that this imbalance could eventually result in a restructuring of the officer's law enforcement role with a diminution in the rehabilitative area. Finally, we will suggest certain historical forces which may mitigate against these trends. (Author abstract)
