A thorough pat search on each inmate is a critical procedure that must be conducted upon entry into the facility and before booking. This ensures the safety and security of the detention environment by identifying and removing any contraband or items that could pose a danger within the facility. The booking process involves collecting identifying information, documenting the charges, and processing the inmate into the system. Conducting a pat search before this process begins is essential, as it prevents any potential issues that could arise during booking and maintains the integrity of the facility's operations.

In contrast, while searches can also occur at different points, such as during release, transfer, or before a trial, the timing associated with the booking process makes it critical to perform a thorough search beforehand. This minimizes risks from the very beginning of the inmate's stay and ensures a systematic approach to their management within the facility.
