Related: Strip search, Contraband, Reasonable suspicion

A search requiring a person to remove some or all clothing so body surfaces can be inspected. Because it is highly intrusive, policy usually requires supervisory approval and documented justification beyond ordinary suspicion.

Related: Pat-down search, Reasonable suspicion, Chain of custody

Related: Use-of-force continuum, Incident report, Objective reasonableness

Selective attention

The mental filter that focuses on one source of information while ignoring others. It helps concentration but causes officers to miss unexpected events, so supervisors rotate tasks and cross-check observations.

Related: Situational awareness, Inattentional blindness
Inattentional blindness

Failing to notice something visible because attention is fixed on a different task, such as missing a weapon while focused on a fight. Deliberate scanning and multiple observers reduce this risk.

Related: Selective attention, Situational awareness

The degree to which a witness's account is accurate, affected by stress, lighting, distance, and time. Officers record descriptions promptly and compare independent accounts rather than trusting a single memory.
