Addressing “Complexities” in Homeland Security


This article investigates a new category of intelligence problems called “complexities”. These complexities include terrorism, terrorist groups, “sensemaking” in the homeland security, and “sensemaking” in the law enforcement. The challenge is what intelligence and other agencies can usefully say about them for policymakers, ranging from senior leaders of government to police on the street. This article first defines complexities and explores their implications, then looks at several examples of how complexities might be addressed in counterterrorism intelligence and law enforcement.
