Please answer the following question: Information:  - A police officer, also known as a policewoman, policeman, police agent is a warranted law employee of a police force. In the United States, "officer" usually is the formal name of the lowest police rank. In many other countries, "officer" is a generic term not specifying a particular rank, and the lowest rank is often "constable". In some nations the use of the rank "officer" is legally reserved for military personnel. Police officers are generally charged with the apprehension of criminals and the prevention and detection of crime, protection and assistance of the general public, and the maintenance of public order. Police officers may be sworn to an oath, and have the power to arrest people and detain them for a limited time, along with other duties and powers. Some police officers may also be trained in special duties, such as counter-terrorism, surveillance, child protection, VIP protection, civil law enforcement, and investigation techniques into major crime including fraud, rape, murder, and drug trafficking. Although many police officers wear a corresponding uniform, some police officers are plain-clothed in order to dissimulate as ordinary citizens.  - Special police (also see Auxiliary police) usually describes a police force or unit within a police force whose duties and responsibilities are significantly different from other forces in the same country or from other police in the same force, although there is no consistent international definition. A special constable, in most cases, is not a member of a special police force; in countries in the Commonwealth of Nations and often elsewhere, a special constable is a voluntary or part-time member of a national or local police force or a person involved in law enforcement who is not a police officer but has some of the powers of a police officer.  - Concurrent jurisdiction exists where two or more courts from different systems simultaneously have jurisdiction over a specific case. This situation leads to forum shopping, as parties will try to have their civil or criminal case heard in the court that they perceive will be most favorable to them.   - Community Safety Accreditation Schemes are a means by which the Chief Constable of a police force in the United Kingdom may grant a limited range of police powers to employees of non-police organisations who contribute towards community safety. Community Safety Accreditation Schemes were created under section 40 of the Police Reform Act 2002. Individuals who have been granted these powers are known under the Act as Accredited Persons.  - In criminal justice, particularly in North America, correction, corrections, and correctional, are umbrella terms describing a variety of functions typically carried out by government agencies, and involving the punishment, treatment, and supervision of persons who have been convicted of crimes. These functions commonly include imprisonment, parole and probation. A typical "correctional institution" is a prison. A "correctional system", also known as a "penal system", thus refers to a network of agencies that administer a jurisdiction's prisons and community-based programs like parole and probation boards;. This system is part of the larger criminal justice system, which additionally includes police, prosecution and courts. Jurisdictions throughout Canada and the US have ministries or departments, respectively, of corrections, correctional services, or similarly-named agencies.  - Michele Marie Leonhart ( born February 27 , 1956 ) is an American career law enforcement officer and the former Administrator of the Drug Enforcement Administration ( DEA ) . After the resignation of Administrator Karen P. Tandy in the fall of 2007 , Leonhart also served as Acting Administrator of the DEA . On February 2 , 2010 , President Barack Obama nominated Leonhart for the position of DEA Administrator . Leonhart 's tenure as DEA Administrator was marked with controversy and scandals including a prostitution scandal ; by the end of her service in April 2015 , she was labelled `` embattled '' when a bipartisan group of lawmakers declared that they had no confidence in her leadership . On April 21 , she conveyed to Attorney General Eric Holder that she intended to resign the following month .  - In the United States, a special agent is usually a detective or investigator for a state, county, municipal, federal, or tribal government who primarily serve in investigatory roles. Within the United States' federal law enforcement system, dozens of federal agencies employ federal law enforcement officers, each with different criteria pertaining to the use of the titles ""Special Agent"" versus ""Agent"". In intelligence usage, agent refers to one who is recruited, trained, controlled and employed to obtain and report information.  - The Controlled Substances Act (CSA) is the statute establishing federal U.S. drug policy under which the manufacture, importation, possession, use and distribution of certain substances is regulated. It was passed by the 91st United States Congress as Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970 and signed into law by President Richard Nixon. The Act also served as the national implementing legislation for the Single Convention on Narcotic Drugs.  - In general, a civilian is "a person who is not a member of the military or of a police or firefighting force", as defined by Merriam Webster's Dictionary. From the perspective of the U.S. Department of Defense, Chapter 18 of Title 10 United States Code refers to non-military law enforcement officers as civilians since they are employees rather than enlisted personnel, and also in order to distinguish itself from military police. In military and law enforcement slang, the term "Civies" or "Civvies" are often used to refer civilian population or civilian clothing.  - The Drug Enforcement Administration (DEA) is a United States federal law enforcement agency under the U.S. Department of Justice, tasked with combating drug smuggling and use within the United States. The DEA is the lead agency for domestic enforcement of the Controlled Substances Act, sharing concurrent jurisdiction with the Federal Bureau of Investigation (FBI), Immigration and Customs Enforcement (ICE), Homeland Security, and the U.S. Border Patrol. It has sole responsibility for coordinating and pursuing U.S. drug investigations both domestic, and abroad.  - The role of Immigration officers is to ensure that immigration legislation is enforced. This can cover the rules of entry for visa applicants, foreign nationals or those seeking asylum at the border, detecting and apprehending those that have breached the border and removing them, or pursuing those in breach of immigration and criminal laws.  - Parole officers and probation officers play a role in the criminal justice systems by supervising offenders released from incarceration or sentenced to non-custodial sanctions such as community service.

He previously served in the U.S. Senate representing Illinois from 2005 to 2008, and in the Illinois State Senate from 1997 to 2004.  - Homeland security is an American umbrella term for "the national effort to ensure a homeland that is safe, secure, and resilient against terrorism and other hazards where American interests, aspirations, and ways of life can thrive to the national effort to prevent terrorist attacks within the United States, reduce the vulnerability of the U.S. to terrorism, and minimize the damage from attacks that do occur."  - The Federal Bureau of Investigation, or FBI, is the domestic intelligence and security service of the United States, which simultaneously serves as the nation's prime federal law enforcement agency. Operating under the jurisdiction of the U.S. Department of Justice, the 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, the FBI has jurisdiction over violations of more than 200 categories of federal crimes.  - A law enforcement officer (LEO) or peace officer, in North American English, is a public-sector employee whose duties primarily involve the enforcement of laws. The phrase can include police officers, municipal law enforcement officers, special police officers, customs officers, state troopers, special agents, special investigators, border patrol officers, immigration officers, court officers, probation officers, parole officers, arson investigators, auxiliary officers, game wardens, sheriffs, corrections, marshals, and deputies. Security guards are civilians and therefore not law enforcement officers, unless they have been granted powers to enforce particular laws, such as those accredited under a Community Safety Accreditation Scheme. Although typically the term "law enforcement officer" refers to those government agents with police powers, prosecutors are also law enforcement officers.  - A sheriff is a government official, with varying duties, existing in some countries with historical ties to England, where the office originated. There is an analogous although independently developed office in Iceland that is commonly translated to English as "sheriff," and this is discussed below.  - Illinois is a state in the midwestern region of the United States, achieving statehood in 1818. It is the 5th most populous state and 25th largest state in terms of land area, and is often noted as a microcosm of the entire country. The word "Illinois" comes from the Algonquin word for "tribe of superior men". With Chicago in the northeast, small industrial cities and great agricultural productivity in central and northern Illinois, and natural resources like coal, timber, and petroleum in the south, Illinois has a diverse economic base and is a major transportation hub. The Port of Chicago connects the state to other global ports from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean, as well as the Great Lakes to the Mississippi River, via the Illinois River. For decades, O'Hare International Airport has been ranked as one of the world's busiest airports. Illinois has long had a reputation as a bellwether both in social and cultural terms and politics.  - An officer is a person who has a position of authority in a hierarchical organization.  - The President of the United States (POTUS) is the elected head of state and head of government of the United States.
