What is one outcome of a thorough walk-through visual inspection?

A thorough walk-through visual inspection primarily aims to identify potential hiding places for items, such as contraband or unauthorized possessions. This process involves closely observing the environment, including areas that might not be immediately visible or accessible. By understanding the layout and detailing any obscure spots, officers can enhance security and ensure that they are aware of any risks or rule violations that may occur within the facility. This proactive approach is essential for maintaining safety and control within correctional or probation facilities, as it helps prevent the introduction or concealment of prohibited items.

The other options may involve various aspects of correctional procedures but are not the key outcomes of a visual inspection. Gathering witness statements pertains more to investigative procedures after an incident, conducting a personal inventory relates to inventory management of personal belongings, and following up with law enforcement is a response action rather than a preventive inspection outcome.
