	Introduction1

Since the 9/11 terrorist attacks, Congress has not only focused considerable attention on how intelligence is collected, analyzed, and disseminated in order to protect the homeland against terrorism, but also what should such intelligence encompass. Prior to 9/11, it was possible to make a distinction between "domestic intelligence"—primarily law enforcement information collected within the United States—and "foreign intelligence"—primarily military, political, and economic intelligence collected outside the country. Today, this distinction is blurred. Threats to the homeland posed by terrorist groups are national security threats, and intelligence collected outside the United States is often very relevant to the threat environment inside the United States and vice versa. Traditional intelligence collection done clandestinely and overtly, largely at the federal level, to inform national-level policymakers is often differentiated from criminal intelligence gathered by a broader set of federal, state, and local actors generally for law enforcement purposes. Some of the similarities between these perceptions include (1) a fundamental belief that intelligence is the first line of defense for the nation, (2) threats to U.S. national security are largely, although not solely, of foreign origin, and (3) there is a national intelligence role for non-traditional players (largely state, local, tribal law enforcement, as well as the private sector), a role in which they make contributions to preventing terrorist attacks or other inimical acts directed against U.S. citizens within the United States. At a policy and, importantly, local level, are non-traditional players viewed by federal personnel as equal partners, and/or "force multipliers?" Moreover, the strategy states that
U.S. intelligence elements must focus their capabilities to ensure that (1) Intelligence elements in the Departments of Justice and Homeland Security are properly resourced and closely integrated within the larger Intelligence Community, (2) all Intelligence Community components assist in facilitating the integration of collection and analysis against terrorists, weapons of mass destruction, and other threats to the homeland, and (3) state, local, and tribal entities and the private sector are connected to our homeland security and intelligence efforts. How the term "connected" is defined becomes of critical importance, as it implies communication and the sharing of information among federal, state, and local intelligence officials. Statutory Definitions of Intelligence and Homeland Security Information

Homeland security intelligence is not a term that is as yet defined or codified in law. The methods of traditional foreign intelligence collection fall into the following five areas: imagery intelligence (IMINT), signals intelligence (SIGINT), human intelligence (HUMINT), measurement and signatures intelligence (MASINT), and open source intelligence (OSINT). Because HSINT is not necessarily source-specific, some would question whether it should be referred to as a collection "discipline." Approaches to Framing Homeland Security Intelligence

There are at least three different constructs that could be used to frame HSINT: (1) geographic (2) structural, and (3) holistic. Under the holistic approach, the HSINT community might include the 16 statutory members of the IC (as each collects national intelligence, or intelligence related to national security which could have a profound impact on homeland security); the National Counterterrorism Center, National Counterintelligence Center, National Counter Proliferation Center, and the Open Source Intelligence Center; the 14 existing private sector Information Sharing and Analysis Centers (ISACS), scores of state and local law enforcement entities charged with gathering criminal intelligence, numerous state and regional "intelligence fusion" centers, and federal entities with law enforcement responsibilities which may collect intelligence related to national security.
Since the 9/11 terrorist attacks, Congress has focused considerable attention on how intelligence is collected, analyzed, and disseminated in order to protect the homeland against terrorist threats. Prior to 9/11, it was possible to make a distinction between "domestic intelligence"—primarily law enforcement information collected within the United States—and "foreign intelligence"—primarily military, political, and economic intelligence collected outside the country. Today, threats to the homeland posed by terrorist groups are now national security threats. Intelligence collected outside the United States is often very relevant to the threat environment inside the United States and vice versa.
Although the activities involved in homeland security intelligence (HSINT) itself are not new, the relative importance of state, local, and private sector stakeholders; the awareness of how law enforcement information might protect national security; and the importance attached to homeland security intelligence have all increased substantially since the events of 9/11.
There are numerous intelligence collection disciplines through which the U.S. Intelligence Community (IC) collects intelligence to support informed national security decision-making at the national level and the allocation of tactical military and law enforcement resources at the local level. The collection disciplines are generally referred to as those which fall within national technical means or non-technical means. Technical means include signals intelligence (SIGINT), measurement and signatures intelligence (MASINT), and imagery intelligence (IMINT). Non-technical means include human intelligence (HUMINT) and open source intelligence (OSINT). Each of these collection disciplines is source-specific—that is, a technical platform or human source, generally managed by an agency or mission manager, collects intelligence that is used for national intelligence purposes.
HSINT, however, is generally not source specific, as it includes both national technical and non-technical means of collection. For example, HSINT includes human intelligence collected by federal border security personnel or state and local law enforcement officials, as well as SIGINT collected by the National Security Agency. Reasonable individuals can differ, therefore, with respect to the question of whether HSINT is another collection discipline, or whether homeland security is simply another purpose for which the current set of collection disciplines is being harnessed. Homeland security information, as statutorily defined, pertains directly to (1) terrorist intentions and capabilities to attack people and infrastructure within the United States, and (2) U.S. abilities to deter, prevent, and respond to potential terrorist attacks.
This report provides a potential conceptual model of how to frame HSINT, including geographic, structural/statutory, and holistic approaches. Given that state, local, tribal, and private sector officials play such an important role in HSINT, the holistic model, one not constrained by geography or levels of government, strikes many as the most compelling. The report argues that there is, in effect, a Homeland Security Intelligence Community (HSIC). Although the HSIC's members are diffused across the nation, they share a common counterterrorism interest. The proliferation of intelligence and information fusion centers across the country indicate that state and local leaders believe there is value to centralizing intelligence gathering and analysis in a manner that assists them in preventing and responding to local manifestations of terrorist threats to their people, infrastructure, and other assets. At the policy and operational levels, the communication and integration of federal HSINT efforts with these state and local fusion centers will likely remain an important priority and future challenge. This report will not be updated.
