Recognizing the Indicators of a Possible Suicide Bomber

Look for combinations, not stereotypes.

Possible warning signs can include unusual bulk or rigidity around the torso that does not fit the setting, repeated adjustment of the same area of clothing, visible wiring or device components, an attempt to defeat screening or enter a restricted area, or behavior that is sharply inconsistent with the surrounding environment. A companion may also try to distract security or draw attention elsewhere.

Nervousness by itself is not enough. Neither is clothing, ethnicity, faith, language, or ordinary use of a phone. The question is whether multiple observable indicators, in context, create a reasonable concern that warrants reporting.

If you are a member of the public.

• Create distance. Do not approach, challenge, restrain, or touch the person or any suspected device.
• Move other people away without creating a crowd. Use calm, direct language.
• Call 911 or notify on-site security. Give the location, a concise description, direction of travel, and the specific behavior or object that concerned you.
• Do not return to retrieve belongings. Follow police, fire, bomb squad, or venue instructions.

If you are responsible for a venue.

Make sure staff know how to report suspicious activity, who can initiate an evacuation or shelter decision, how to reach 911 without delay, and where people should move if an area must be cleared. Train against observable behavior and objects rather than demographic profiles.

Recognition is about buying time and distance. Your job is not to confirm the threat yourself.
