Indicators and Warnings

Lead Instructor:  Alon Stivi
 Access:  All   Status:  Active    Individual Lesson Price: $0

Acts of violence and Active Shooter attacks are not random or unpredictable. They are often the outcome of a long process and provide warning signs that are often ignored or misunderstood.

In order to prevent attacks, we must recognize risk factors, violence tendencies and behavioral indicators. Understanding attack pre-cursors provide early warning and can allow institutions to help troubled individuals and prevent attacks. Recognizing improvised, concealed and disguised weapons and knowing how to communicate security concerns is essential.

In order to prevent attacks, we must remain vigilant and correlate Essential Elements of Information (EEI). The objectives are to identify Persons of Interest (POI) that exhibit suspicious behavior and/or recognize Out Of Ordinary Occurrences (O4) that may signs of an imminent attack. Once a potential threat has been identified, we must alert others and inform the authorities in a timely manner. Doing so effectively will assist Law Enforcement with investigation and to determine the credibility of the threat.
