Drug Enforcement Administration (DEA).

The Drug Enforcement Administration, or DEA, is the leading law enforcement agency responsible for preventing the distribution of illegal narcotics in the United States. 

The mission of the Drug Enforcement Administration (DEA) is to enforce the controlled substances laws and regulations of the United States and bring to the criminal and civil justice system of the United States, or any other competent jurisdiction, those organizations and principal members of organizations, involved in the growing, manufacture, or distribution of controlled substances appearing in or destined for illicit traffic in the United States; and to recommend and support non-enforcement programs aimed at reducing the availability of illicit controlled substances on the domestic and international markets.

In carrying out its mission as the agency responsible for enforcing the controlled substances laws and regulations of the United States, the DEA’s primary responsibilities include:

  • Investigation and preparation for the prosecution of major violators of controlled substance laws operating at interstate and international levels.
  • Investigation and preparation for prosecution of criminals and drug gangs who perpetrate violence in our communities and terrorize citizens through fear and intimidation.
  • Management of a national drug intelligence program in cooperation with federal, state, local, and foreign officials to collect, analyze, and disseminate strategic and operational drug intelligence information.
  • Seizure and forfeiture of assets derived from, traceable to, or intended to be used for illicit drug trafficking.
  • Enforcement of the provisions of the Controlled Substances Act as they pertain to the manufacture, distribution, and dispensing of legally produced controlled substances.
  • Coordination and cooperation with federal, state and local law enforcement officials on mutual drug enforcement efforts and enhancement of such efforts through exploitation of potential interstate and international investigations beyond local or limited federal jurisdictions and resources.
  • Coordination and cooperation with federal, state, and local agencies, and with foreign governments, in programs designed to reduce the availability of illicit abuse-type drugs on the United States market through nonenforcement methods such as crop eradication, crop substitution, and training of foreign officials.
  • Responsibility, under the policy guidance of the Secretary of State and U.S. Ambassadors, for all programs associated with drug law enforcement counterparts in foreign countries.
  • Liaison with the United Nations, Interpol, and other organizations on matters relating to international drug control programs.

Homeland Security.

This Federal Law Enforcement Agency has 5 primary duties:

Protecting the American people from terrorist threats is the founding principle of the Department and our highest priority. This is an effort where everyone–families and communities, first responders, the private sector, state and local governments, as well as the Department–must contribute. My approach is simple: direct every resource available towards prevention and preparedness, and ask Americans to live in a constant state of readiness, not a constant state of fear.

Since January, we have forged new partnerships with our international allies to provide more tools in the fight against terrorism. We have dedicated new resources to detect threats at our transportation hubs and protect our critical infrastructure. And, we are strengthening information-sharing efforts, working hand-in-hand with state, local and tribal law enforcement.

Fulfilling our mission also means securing our borders—our Southern border, our Northern border, and our air and sea ports. Every year, we apprehend and deport more than one million illegal immigrants, no doubt deterring countless more from trying to cross the border. Recently, we announced a new initiative to strengthen security on the Southwest border to disrupt the drug, cash and weapon smuggling that is helping to fuel cartel violence in Mexico.

When it comes to immigration, we need to facilitate legal immigration while we crack down on those who violate our nation’s laws. A few weeks ago, we issued new guidance to our agents in the field to focus our efforts on apprehending criminal illegal aliens and prosecuting employers who knowingly hire illegal workers. At the same time, we are committed to providing employers with the most up-to-date and effective resources to maintain a legal workforce. This new focus is drawing widespread praise–from law enforcement to the business community–because it addresses the root cause of illegal immigration.

As a nation, we must develop a more urgent sense of readiness. Hurricanes happen. Tornadoes happen. Floods happen. And as we recently experienced, so do health outbreaks like the H1N1 flu. The Department plays a critical role in helping communities in all stages of a disaster–preparation, response and long term recovery. Since January, we have worked in close coordination with state and local authorities to respond to severe storms in Arkansas, Kentucky, and Missouri and flooding in North Dakota and Minnesota. We have taken bold new steps to accelerate recovery efforts in the Gulf Coast region, streamlining decision making and consolidating offices to eliminate redundancies.

And we took immediate and aggressive steps to lead the federal government’s efforts to confront the H1N1 flu outbreak.

Finally, we must unify and mature our Department. Our goal is simple: one DHS, one enterprise, a shared vision, with integrated results-based operations. Through a consolidated headquarters, we are bringing 35 locations together. We have launched an expansive efficiency initiative that is leveraging the economies of scale in our Department in order to recover hundreds of millions of dollars and create a culture of responsibility and fiscal discipline.

Throughout these five priority areas, we are applying a series of cross-cutting approaches. We are bolstering cooperation with our partners at the local, tribal, state, federal and international levels; we are expanding our capabilities through the deployment of science and technology while developing and maturing new technologies for tomorrow; and we are maximizing efficiency to ensure every security dollar is spent in the most effective way.

We cannot afford to relent on any of these five fronts because together, they amount to our one overarching mission—a mission whose scope is massive, challenging, and humbling, but also a mission so straightforward and clear that it is contained in our name: securing the homeland.

Federal Bureau of Investigation (FBI).

The mission of the FBI is to protect and defend the United States against terrorist and foreign intelligence threats, to uphold and enforce the criminal laws of the United States, and to provide leadership and criminal justice services to federal, state, municipal, and international agencies and partners; and to perform these responsibilities in a manner that is responsive to the needs of the public and is faithful to the Constitution of the United States.

The FBI’s major priorities are to:

  • Protect the United States from terrorist attack;
  • Protect the United States against foreign intelligence operations and espionage;
  • Protect the United States against cyber-based attacks and high-technology crimes;

In furtherance of this function, the FBI designs, develops, and implements counterterrorism initiatives which enhance the FBI’s ability to minimize the terrorist threat.
  • Conduct counterintelligence activities and coordinate counterintelligence activities of other agencies in the intelligence community within the United States. (Executive Order 12333 includes international terrorist activities in its definition of counterintelligence.)
  • Coordinate the efforts of U.S. Government agencies and departments in protecting the nation’s critical infrastructure by identifying and investigating criminal and terrorist group intrusions through physical and cyber attacks.
  • Investigate violations of the laws of the United States and collect evidence in cases in which the United States is or may be a party in interest, except in cases in which such responsibility is by statute or otherwise specifically assigned to another investigative agency.
  • Locate and apprehend fugitives for violations of specified federal laws and, when so requested, state and local fugitives pursuant to federal statutory authority.
  • Conduct professional investigations to identify, disrupt, and dismantle existing and emerging criminal enterprises whose activities affect the United States. Address international criminal organizations and terrorist groups, which threaten the American people and their property, through expanded international liaison and through the conduct of extraterritorial investigations as mandated by laws and Executive Orders.
  • Gather, analyze and assess information and intelligence of planned or committed criminal acts.
  • Establish and implement quality outreach programs that will ensure FBI and community partnerships and sharing.
  • Conduct personnel investigations requisite to the work of the Department of Justice and whenever required by statute or otherwise.
  • Establish and conduct law enforcement training programs and conduct research to provide assistance to state and local law enforcement personnel. Participate in interagency law enforcement initiatives which address crime problems common to federal/state/local agencies.
  • Develop new approaches, techniques, systems, equipment and devices to improve and strengthen law enforcement and assist in conducting state, local and international law enforcement training programs.
  • Provide timely and relevant criminal justice information and identification services concerning individuals, stolen property, criminal organizations and activities, crime statistics, and other law enforcement related data, not only to the FBI, but to qualified law enforcement, criminal justice, civilian, academic, employment, licensing, and firearms sales organizations.
  • Operate the Federal Bureau of Investigation Laboratory not only to serve the FBI, but also to provide, without cost, technical and scientific assistance, including expert testimony in federal or local courts, for all duly constituted law enforcement agencies, other organizational units of the Department of Justice, and other federal agencies; and to provide identification assistance in mass disasters and for other humanitarian purposes.
  • Review and assess operations and work performance to ensure compliance with laws, rules, and regulations and to ensure efficiency, effectiveness, and economy of operations.
  • Effectively and appropriately communicate and disclose information on the FBI mission, accomplishments, operations, and values to Congress, the media, and the public.

United States Marshals Service (USMS).

The U.S. Marshals Service is the nation’s oldest and most versatile federal law enforcement agency. Federal Marshals have served the country since 1789, oftentimes in unseen but critical ways. To this day, the Marshals occupy a uniquely central position in the federal justice system. It is the enforcement arm of the federal courts, and as such, it is involved in virtually every federal law enforcement initiative.

Presidentially appointed U.S. Marshals direct the activities of 94 districts — one for each federal judicial district. More than 3,752 Deputy Marshals and Criminal Investigators form the backbone of the agency. Among their many duties, they apprehend more than half of all federal fugitives, protect the federal judiciary, operate the Witness Security Program, transport federal prisoners and seize property acquired by criminals through illegal activities.

Judicial Security

Protection of federal judicial officials, which includes judges, attorneys and jurors, holds a high priority with the Marshals Service. Deputy marshals use the latest security techniques and devices at highly sensitive trials throughout the nation. Fully-trained, contract officers comprise the agency’s Court Security Officer (CSO) Program. These specially deputized officers have full law enforcement authority and occupy a vital role in courthouse security. The Marshals Service protects more than 2,000 sitting judges and countless other court officials at more than 400 court facilities throughout the nation.

The Marshals Service also oversees each aspect of courthouse construction projects, from design through completion, to ensure the safety of federal judges, court personnel and the public.

Fugitive Operations

In fiscal year 2015, the Marshals apprehended more than 33,300 federal fugitives, clearing approximately 36,600 felony warrants.

Working with authorities at the federal, state, and local levels, U.S. Marshals-led fugitive task forces arrested more than 99,700 state and local fugitives, clearing 119,173 state and local felony warrants.

The U.S. Marshals Service works with the international law enforcement community to apprehend fugitives abroad as well as to seek foreign fugitives living or residing in the United States. In FY 2015, the Marshals coordinated 796 extraditions and deportations.

The agency has four foreign field offices in Jamaica, Mexico, the Dominican Republic and Colombia. The U.S. Marshals work closely with law enforcement agencies along the borders of Mexico and Canada and with the Department of State’s Diplomatic Security Service. The agency also holds key positions at Interpol.

The Marshals use both traditional methods and sophisticated technologies for fugitive investigations, including tactical equipment, electronic surveillance and aerial surveillance. Tactical equipment includes covert audio and video alarms and sensors; digital, narrowband, encrypted wireless communications; and radio and satellite communications equipment, such as tactical repeaters, base stations and portable tower trailers.

Witness Security

The Marshals Service provides for the security, health and safety of government witnesses — and their immediate dependents — whose lives are in danger as a result of their testimony against drug traffickers, terrorists, organized crime members and other major criminals.

Since 1971, the Marshals Service has protected, relocated and given new identities to over 8,600 witnesses and 9,900 of their family members. The successful operation of the Witness Security Program have been generally recognized as providing a unique and valuable tool in the government’s war against major criminal enterprises.

Prisoner Operations

The Marshals Service houses over 51,800 detainees in federal, state, local and private jails throughout the nation. In order to house these pre-sentenced prisoners, the Marshals Service contracts with approximately 1,800 state and local governments to rent jail space. Eighty percent of the prisoners in Marshals Service custody are detained in state, local and private facilities; the remainder are housed in Federal Bureau of Prisons (BOP) facilities.

In areas where detention space is scarce, the Marshals Service uses Cooperative Agreement Program (CAP) funds to improve local jail conditions and expand jail capacities in return for guaranteed space for federal prisoners.

Justice Prisoner and Alien Transportation System

In 1995, the air fleets of the Marshals Service and the Bureau of Immigration and Customs Enforcement (ICE) merged to create the Justice Prisoner and Alien Transportation System (JPATS). The merger created a more efficient and effective system for transporting prisoners and criminal aliens. Operated by the Marshals Service, JPATS is one of the largest transporters of prisoners in the world, handling more than 700 requests every day to move prisoners between judicial districts, correctional institutions and foreign countries. On average, more than 260,000 prisoner and alien movements a year are completed by JPATS via coordinated air and ground systems.

Asset Forfeiture

The Marshals Service is responsible for managing and disposing seized and forfeited properties acquired by criminals through illegal activities. Under the auspices of the Department of Justice Asset Forfeiture Program, the Marshals Service currently manages more than $3.1 billion worth of property, and it promptly disposes of assets seized by all Department of Justice agencies. The goal of the program is to maximize the net return from seized property and then to use the property and proceeds for law enforcement purposes.

Service of Court Process

Historically, the U.S. Marshals Service has taken responsibility for serving most Federal court criminal process. However, the courts have become more receptive to other law enforcement personnel serving criminal process. The Federal Rules of Civil Procedure, Rules 4 and 4.1, and Rule E(4) of the Supplemental Rules for Certain Admiralty and Maritime Claims, clearly define the cases in which the USMS is responsible for service of civil process and the manner in which such service will be made.

Tactical Operations

Deputy marshals carry out hundreds of special missions each year that are related to the Marshals Service’s broad federal law enforcement and judicial security responsibilities.

The Special Operations Group is a highly trained force of deputy marshals with the responsibility and capability of responding to emergency situations where federal law is violated or where federal property is endangered. Most SOG members are full-time deputy marshals stationed in district offices throughout the nation. They remain on call 24 hours a day for SOG missions. Specially trained deputy marshals provide security and law enforcement assistance to the Department of Defense and the U.S. Air Force when Minuteman and cruise missiles are moved between military facilities.

The Office of Emergency Management is the primary point of contact when the Marshals Service is involved in sensitive and classified missions. It has primary responsibility over the agency’s actions involving homeland security, national emergencies and domestic crises.
