Which of the following is NOT listed as a factor that should raise awareness of possible terrorism involvement?

• A. Occupancy or location
• B. Timing of event
• C. On-scene warning signs
• D. Past incidents of a similar type

Answer: (D)

Indicators that should alert responders to potential terrorism involvement come from what you can observe or infer at the scene. Occupancy or location matters because a crowded venue or a location that’s a known high-value target can heighten risk. Timing of the event matters because unusual or targeted timing can signal planning and intention. On-scene warning signs are crucial—things like unattended packages, suspicious devices, odd behavior, or anything that seems out of place or designed to cause disruption. Past incidents of a similar type are not observable at the moment and don’t serve as a real-time cue to raise awareness; they relate to history rather than what you encounter at the scene.
