The Seven Signs of Terrorism

1. Surveillance

Someone recording or monitoring activities. This may include the use of cameras (either still or video), note taking, drawing diagrams, annotation on maps, or using binoculars or other vision enhancing devices.

2. Information Gathering

People or organizations attempting to gain information about military operations, law enforcement, other emergency responders, critical infrastructure, or large gatherings of people.

3. Testing Security (probing)

Any attempt to measure reaction times to security breaches, or to penetrate physical security barriers or procedures in order to assess strengths or weaknesses.

4. Planning (acquiring supplies/funding)

Purchasing or stealing explosives, weapons, ammunition, etc. Also includes acquiring uniforms, passes, or badges (or equipment to manufacture such items) or any other controlled items.

5. Suspicious Behavior

People or items that don’t seem to belong in the workplace, neighborhood, business establishment, or anywhere else.

6. Rehearsal or Trial Runs

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 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. Getting into Position

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.
