The threats facing our nation are ever changing. Our greatest defense against emerging threats is effective communication between Americans and law enforcement agencies. Local residents know their communities better than any government organization ever will. Ordinary residents and visitors are positioned to observe and report suspicious behaviors that may be attributed to national security threats. Every person plays a vital role in keeping our nation safe against terror attacks, and other mass casualty incidents like active shooter events, by remaining vigilant to suspicious behaviors.

Many concerning behaviors observed by residents or visitors may be constitutionally protected acts. Therefore, it is essential to report suspicious behaviors with a potential for mass violence and not report individuals based on demographics. When in doubt, report suspicious behaviors to Delaware’s Anti-Terrorism Tip Line at 1-800-FORCE-12 (1-800-367-2312) or via email to Received tips will be reviewed by Delaware’s Homeland Security based fusion center, the Delaware Information and Analysis Center (DIAC) (link opens in new tab). The DIAC will review all tips and forward those with reasonable suspicion to the FBI-Joint Terrorism Task Force and the U.S. Department of Homeland Security for follow-up investigation. All emergencies and any in-progress events should always be reported immediately to the local 911 center.

Groups seeking Violent Intruder Preparedness and Response (VIPR) training may contact the DIAC via email at to request a training session. VIPR training provides instruction on responsible suspicious activity reporting, pre-incident indicators and preparedness, and response to active shooter events.  Preparing today may save lives tomorrow, should a catastrophic incident occur in a Delaware community. Preparedness is the key factor to increase situational awareness and survivability. Remember to be vigilant and do your part to keep America safe.
