Question: What kind of agency is the employer of Eric O'Neill?

full_context: Document 1: Federal Bureau of Investigation: Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort (the Venona project)—with which the FBI was heavily involved—broke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project but failed to notify the Central Intelligence Agency (CIA) until 1952. Another notable case is the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.
Document 2: Federal Bureau of Investigation: During the September 11, 2001 attacks on the World Trade Center, FBI agent Leonard W. Hatton Jr. was killed during the rescue effort while helping the rescue personnel evacuate the occupants of the South Tower and stayed when it collapsed. Within months after the attacks, FBI Director Robert Mueller, who had been sworn in a week before the attacks, called for a re-engineering of FBI structure and operations. He made countering every federal crime a top priority, including the prevention of terrorism, countering foreign intelligence operations, addressing cyber security threats, other high-tech crimes, protecting civil rights, combating public corruption, organized crime, white-collar crime, and major acts of violent crime.
Document 3: Federal Bureau of Investigation: Between 1993 and 1996, the FBI increased its counter-terrorism role in the wake of the first 1993 World Trade Center bombing in New York City, New York; the 1995 Oklahoma City bombing in Oklahoma City, Oklahoma; and the arrest of the Unabomber in 1996. Technological innovation and the skills of FBI Laboratory analysts helped ensure that the three cases were successfully prosecuted. Justice Department investigations into the FBI's roles in the Ruby Ridge and Waco incidents were found to be obstructed by agents within the Bureau. During the 1996 Summer Olympics in Atlanta, Georgia, the FBI was criticized for its investigation of the Centennial Olympic Park bombing. It has settled a dispute with Richard Jewell, who was a private security guard at the venue, along with some media organizations, in regard to the leaking of his name during the investigation.
Document 4: Kill or Capture: How a Special Operations Task Force Took Down a Notorious al Qaeda Terrorist: Kill or Capture: How a Special Operations Task Force Took Down a Notorious al Qaeda Terrorist is a book published by Macmillan Publishing in early 2011. The author, a former interrogator, criticizes the use of ""extended interrogation techniques"".
Document 5: Federal Bureau of Investigation: The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States, which simultaneously serves as the nation's prime federal law enforcement organization. Operating under the jurisdiction of the U.S. Department of Justice, FBI is concurrently a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A leading U.S. counterterrorism, counterintelligence, and criminal investigative organization, FBI has jurisdiction over violations of more than 200 categories of federal crimes.
Document 6: Robert Ressler: Robert Kenneth Ressler (February 21, 1937 -- May 5, 2013) was an FBI agent and author. He played a significant role in the psychological profiling of violent offenders in the 1970s and is often credited with coining the term ``serial killer. ''After retiring from the FBI, he authored a number of books on serial murders, and often gave lectures on criminology.
Document 7: Federal Bureau of Investigation: The FBI is headquartered at the J. Edgar Hoover Building in Washington, D.C., with 56 field offices in major cities across the United States. The FBI also maintains over 400 resident agencies across the United States, as well as over 50 legal attachés at United States embassies and consulates. Many specialized FBI functions are located at facilities in Quantico, Virginia, as well as a "data campus" in Clarksburg, West Virginia, where 96 million sets of fingerprints "from across the United States are stored, along with others collected by American authorities from prisoners in Saudi Arabia and Yemen, Iraq and Afghanistan." The FBI is in process of moving its Records Management Division, which processes Freedom of Information Act (FOIA) requests, to Winchester, Virginia.
Document 8: Central Intelligence Agency: Unlike the Federal Bureau of Investigation (FBI), which is a domestic security service, CIA has no law enforcement function and is mainly focused on overseas intelligence gathering, with only limited domestic collection. Though it is not the only U.S. government agency specializing in HUMINT, CIA serves as the national manager for coordination and deconfliction of HUMINT activities across the entire intelligence community. Moreover, CIA is the only agency authorized by law to carry out and oversee covert action on behalf of the President, unless the President determines that another agency is better suited for carrying out such action. It can, for example, exert foreign political influence through its tactical divisions, such as the Special Activities Division.
Document 9: Federal Bureau of Investigation: Although many of FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection overseas, FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in lesser cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the Director of National Intelligence.
Document 10: Federal Bureau of Investigation: Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across the globe. These overseas offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA has a limited domestic function; these activities generally require coordination across government agencies.
Document 11: Federal Bureau of Investigation: On July 8, 2007 The Washington Post published excerpts from UCLA Professor Amy Zegart's book Spying Blind: The CIA, the FBI, and the Origins of 9/11. The Post reported from Zegart's book that government documents show the CIA and FBI missed 23 potential chances to disrupt the terrorist attacks of September 11, 2001. The primary reasons for the failures included: agency cultures resistant to change and new ideas; inappropriate incentives for promotion; and a lack of cooperation between the FBI, CIA and the rest of the United States Intelligence Community. The book blamed the FBI's decentralized structure, which prevented effective communication and cooperation among different FBI offices. The book suggested that the FBI has not evolved into an effective counter-terrorism or counter-intelligence agency, due in large part to deeply ingrained agency cultural resistance to change. For example, FBI personnel practices continue to treat all staff other than special agents as support staff, classifying intelligence analysts alongside the FBI's auto mechanics and janitors.
Document 12: Eric O'Neill: Eric Michael O'Neill (born March 3, 1973) is an American former FBI counter-terrorism and counterintelligence operative. He worked and was entitled as an Investigative Specialist with the Special Surveillance Group (SSG) and played a major role in the arrest, conviction, and life imprisonment of FBI agent Robert Hanssen for spying on behalf of the Soviet Union and the Russian Federation. His book written about this experience, Gray Day: My Undercover Mission to Expose America's First Cyber Spy, was published in spring 2019. He is a public speaker and security expert who currently lectures internationally about espionage and national security, cybersecurity, fraud, corporate diligence and defense, hacking, pursuing dreams and surviving Hollywood.
Document 13: Federal Bureau of Investigation: The FBI director is responsible for the day-to-day operations at the FBI. Along with his deputies, the director makes sure cases and operations are handled correctly. The director also is in charge of making sure the leadership in any one of the FBI field offices is manned with qualified agents. Before the Intelligence Reform and Terrorism Prevention Act was passed in the wake of the September 11 attacks, the FBI director would directly brief the President of the United States on any issues that arise from within the FBI. Since then, the director now reports to the Director of National Intelligence (DNI), who in turn reports to the President.
Document 14: Federal Bureau of Investigation: The FBI often works in conjunction with other Federal agencies, including the U.S. Coast Guard (USCG) and U.S. Customs and Border Protection (CBP) in seaport and airport security, and the National Transportation Safety Board in investigating airplane crashes and other critical incidents. Immigration and Customs Enforcement Homeland Security Investigations (ICE-HSI) has nearly the same amount of investigative man power as the FBI, and investigates the largest range of crimes. In the wake of the September 11 attacks, then-Attorney General Ashcroft assigned the FBI as the designated lead organization in terrorism investigations after the creation of the U.S. Department of Homeland Security. ICE-HSI and the FBI are both integral members of the Joint Terrorism Task Force.
Document 15: Tinker Tailor Soldier Spy: It is 1973, the height of the Cold War. George Smiley, former senior official of Britain's Secret Intelligence Service (known as ``the Circus ''because its London office is at Cambridge Circus), has been living in unhappy retirement for a year after an operation in Czechoslovakia, codenamed Testify, ended in disaster with the capture and torture of agent Jim Prideaux. The failure resulted in the dismissals of Smiley and his superior, Control, the head of the Circus. Smiley is unexpectedly approached by Peter Guillam, his former protege at the Circus, and Under - Secretary Oliver Lacon, the Civil Service officer responsible for overseeing the Circus. At Lacon's home they meet with Ricki Tarr, a Circus agent who had been missing for months and had been declared persona - non-grata upon suspicion of having defected to Moscow. Tarr tells them of the existence of a Soviet mole at the highest level of the Circus. The mole is codenamed Gerald and is handled by Moscow Centre's agent, Polyakov, stationed at the Soviet embassy in London. Tarr tells them that when he obtained this information from a female Russian diplomat visiting Hong Kong and informed London, the woman was forcibly returned to Moscow. Tarr, realising someone in London had betrayed him, went on the run, eventually coming out to contact his former boss Guillam, the only person in the Circus he could trust.
