Seven Signs of Terrorism
(from a Department of Defense poster)
Surveillance: Someone recording or monitoring
activities. This may include the use of cameras (either still or
video), note taking, drawing diagrams, annotating on maps, or using
binoculars or other vision-enhancing devices.
2. Elicitation: People or organizations attempting to gain
information about military operations, capabilities, or people.
Elicitation attempts may be made by mail, fax, telephone, or in
3. Tests of security: Any attempts to measure reaction times
to security breaches or to penetrate physical security barriers
or procedures in order to assess strengths and weaknesses.
4. Acquiring supplies: Purchasing or stealing explosives,
weapons, ammunition, etc. Also includes acquiring military uniforms,
decals, flight manuals, passes or badges (or the equipment to manufacture
such items) or any other controlled items.
5. Suspicious persons out of place: People who don't seem
to belong in the workplace, neighborhood, business establishment,
or anywhere else. Includes suspicious border crossings and stowaways
aboard ship or people jumping ship in port.
6. Dry run/Trial run: Putting people into position and moving
them around according to their plan without actually committing
the terrorist act. This is especially true when planning a kidnapping,
but it can also pertain to bombings. An element of this activity
could also include mapping out routes and determining the timing
of traffic lights and flow.
7. Deploying assets: People and supplies getting into position
to commit the act. This is a person's last chance to alert authorities
before the terrorist act occurs.
