In what scenario is it necessary to pat down visitors?

Patting down visitors is essential after receiving a credible tip regarding weapons or narcotics. This scenario heightens the risk that individuals may bring contraband into a secured facility, which poses a threat to the safety and security of both staff and inmates. Conducting a pat-down in this context is a proactive measure to prevent the introduction of illegal items, ensuring the integrity of the facility.

While other scenarios, such as entering a secure area or routine security checks, may warrant inspections or searches, the specific nature of a credible tip directly relates to an identified threat level. It necessitates immediate action to address potential risks effectively. Additionally, during the arrival of a new inmate is primarily focused on the intake process rather than monitoring visitors, making it less relevant to the question of visitor searches.
