What Should I Do?

Be Part of the Solution

  • Require valid ID from all new customers.
  • Keep records of purchases.
  • Talk to customers, ask questions, and listen to and observe their responses.
  • Watch for people and actions that are out of place.
  • Make note of suspicious statements, people, and/or vehicles.
  • If something seems wrong, notify law enforcement authorities.

Do not jeopardize your safety or the safety of others.

Preventing terrorism is a community effort. By learning what to look for, you can make a positive contribution in the fight against terrorism. The partnership between the community and law enforcement is essential to the success of anti-terrorism efforts.

Some of the activities, taken individually, could be innocent and must be examined by law enforcement professionals in a larger context to determine whether there is a basis to investigate. The activities outlined on this handout are by no means all-inclusive but have been compiled from a review of terrorist events over several years.
