Under what circumstance can a Protective Security Officer detain someone?

A Protective Security Officer (PSO) can detain someone if it is necessary to ensure order and safety. This principle reflects the core responsibilities of a PSO, which include maintaining a secure environment and protecting federal properties and personnel. The authority to detain is grounded in the need to prevent potential harm or disorder, which encompasses situations where an individual poses a threat to themselves or others, or disrupts the safety and security of the premises.

The emphasis on "necessary to ensure order and safety" underscores the balance that PSOs must maintain between enforcing security protocols and respecting individual rights. Their role often requires quick decision-making in high-pressure situations, and their training prepares them to assess threats swiftly and make judicious choices about when to intervene.

In contrast, being armed does not automatically confer the authority to detain; rather, the context of safety and order is paramount. Likewise, suspicion of guilt without a clear indication of potential harm does not justify detention; mere suspicion may not meet the legal thresholds required for such action. Lastly, while a request from a federal agency might warrant action, the foundational responsibility for ensuring safety establishes the primary grounds for a PSO's authority to detain an individual.
