The federal government uses pattern of life (POL) analysis to identify and track individuals and groups of interest. POL analysis involves collecting and analyzing data on a person's or group's movements, routines, and activities. This data can be collected from a variety of sources, including surveillance cameras, license plate readers, credit card records, and social media.
POL analysis can be used to gather intelligence on foreign governments and individuals. For example, the CIA might use POL analysis to track the movements of a foreign government official in order to identify their contacts and meeting places.
POL analysis can be used to identify and track suspected terrorists. For example, the FBI might use POL analysis to track the movements of a known terrorist suspect in order to identify their associates and potential targets.
