Indicators

There are various indicators of potential concern. However, exhibiting one or more of these characteristics or behaviors does not necessarily mean someone will become a threat or turn violent. The FBI has provided examples of personality characteristics and behaviors that may indicate a cause for concern (see below). This list is not meant to be all-inclusive or a checklist, nor should it be used to profile individuals. Personality characteristics and behaviors must always be examined in context.
