If You See Something Say Something

What is a “Suspicious activity?”

A Suspicious Activity: is any observed behavior that could indicate terrorism or terrorism-related crime. This includes, but is not limited to:

• Unusual or unique items or situations: A car that is parked in an odd location, a package/luggage that is unattended, a window/door that is open when it is usually closed, or other out-of-the-ordinary situations.

• Eliciting information: A person questions individuals at a level beyond curiosity about a building’s purpose, operations, security procedures and/or personnel, shift changes, etc.

• Observation/surveillance: Someone pays unusual attention to facilities or buildings beyond a casual or professional interest. This includes extended loitering without explanation (particularly in concealed locations); unusual, repeated, and/or prolonged observation of a building (e.g., with binoculars or video camera); taking notes or measurements; counting paces; sketching floor plans, etc.

Some of these activities could be innocent—it's up to law enforcement to determine whether the behavior warrants investigation. The activities above are not all-inclusive, but have been compiled based on studies of pre-operational aspects of both successful and thwarted terrorist events over several years.SeeSay IndicatorInfographic
