Suspicious Activity Reporting Indicators, Behaviors, and Examples

These tools for analysts and investigators detail potential criminal or noncriminal activities requiring additional information during the vetting process or investigation, as well as defined criminal activity and potential terrorism nexus activity. When the activity involves behavior that may be lawful or is a constitutionally protected activity, the investigating law enforcement agency will carefully assess the information and gather as much information as possible before taking any action, including documenting and validating the information as terrorism-related and sharing it with other law enforcement agencies.
