Fugitive in the context of Fethullah Gülen

A random checkpoint is a military and police tactic. In a military context, checkpoints involve the setup of a hasty roadblock by mobile truck- or armored vehicle-mounted infantry to disrupt unauthorized or unwanted movement or military activity and to check for valid identification and search for contraband, fugitives, or weapons that are not permitted in civilian hands. Random checkpoints are set up to achieve surprise, as opposed to known permanently located checkpoints, which suspects could avoid. They are often established in locations where they cannot be observed by approaching traffic until it is too late to withdraw and escape without being observed.

Patrol car-equipped police units regularly use random checkpoints to detect drivers who are suspected of impaired driving. Police also use hastily set up roadblocks to check cars and car trunks when they are pursuing an armed and dangerous fugitive. As with military checkpoints, sobriety checkpoints and fugitive roadblock searches are located in an area where drivers cannot see the checkpoint until it is too late to withdraw, and checkpoints are only set up on a temporary basis.

The FBI Ten Most Wanted Fugitives is a most wanted list maintained by the United States's Federal Bureau of Investigation (FBI). The list arose from a conversation held in late 1949 between J. Edgar Hoover, Director of the FBI, and William Kinsey Hutchinson, International News Service (the predecessor of the United Press International) editor-in-chief, who were discussing ways to promote capture of the FBI's "toughest guys". This discussion turned into a published article, which received so much positive publicity that on March 14, 1950, the FBI officially announced the list to increase law enforcement's ability to capture dangerous fugitives. The first person added to the list was Thomas J. Holden, a robber and member of the Holden–Keating Gang on the day of the list's inception.

Individuals are generally only removed from the list if they are captured, dead, or if the charges against them are dropped; they are then replaced by a new entry selected by the FBI. In eleven cases, the FBI removed individuals from the list after deciding that they were no longer a "particularly dangerous menace to society". Machetero member Víctor Manuel Gerena, added to the list in 1984, was on the list for 32 years, which was longer than anyone else. Billie Austin Bryant spent the shortest amount of time on the list, being listed for two hours in 1969. The oldest person to be added to the list was Eugene Palmer on May 29, 2019, at 80 years old. On rare occasions, the FBI will add a "Number Eleven" if that individual is extremely dangerous but the Bureau does not feel any of the current ten should be removed. Despite occasional references in the media, the FBI does not rank their list; no suspect is considered "#1 on the FBI's Most Wanted List" or "The Most Wanted".

A bounty is a payment or reward of money to locate, capture or kill an outlaw or a wanted person. Two modern examples of bounties are the ones placed for the capture of Saddam Hussein and his sons by the United States government and Microsoft's bounty for computer virus creators. Those who make a living by pursuing bounties are known as bounty hunters.

Bounties have also been granted for other actions, such as exports under mercantilism.

The United States Marshals Service (USMS) is a federal law enforcement agency in the United States. The Marshals Service serves as the enforcement and security arm of the U.S. federal judiciary. It is an agency of the U.S. Department of Justice and operates under the direction of the U.S. attorney general. U.S. Marshals are the original U.S. federal law enforcement officers, created by the Judiciary Act of 1789 during the presidency of George Washington as the "Office of the United States Marshal" under the U.S. district courts. The USMS was established in 1969 to provide guidance and assistance to U.S. Marshals throughout the federal judicial districts.

The Marshals Service is primarily responsible for locating and arresting federal suspects, the administration of fugitive operations, the management of criminal assets, the operation of the United States Federal Witness Protection Program and the Justice Prisoner and Alien Transportation System, the protection of federal courthouses and judicial personnel, and the protection of senior government officials through the Office of Protective Operations. Throughout its history the Marshals have also provided unique security and enforcement services including protecting African American students enrolling in the South during the civil rights movement, escort security for United States Air Force LGM-30 Minuteman missile convoys, law enforcement for the United States Antarctic Program, and protection of the Strategic National Stockpile.

A most wanted list is a list of criminals and alleged criminals who are believed to be at large and are identified as a law enforcement agency's highest priority for capture. The list can alert the public to be watchful, and generates publicity for the agency.

Víctor Manuel Gerena (born June 24, 1958) is an American fugitive wanted by the FBI for the September 1983 White Eagle armed robbery, as a Wells Fargo employee and a member of the Boricua Popular Army, of a Wells Fargo armored car facility. The more than US$7 million (equivalent to more than $22.1 million in 2024) was the largest cash robbery in U.S. history at that time.

On May 14, 1984, Gerena became the 386th fugitive to be placed on the FBI's Top Ten Most Wanted Fugitives list. He remains at large, and on April 11, 2010, became the fugitive to have spent the most time on the list, surpassing Donald Eugene Webb, who was removed from the list on March 31, 2007, after 25 years, 10 months, and 27 days after Webb was presumed dead. Gerena was removed from the list on December 15, 2016, after 32 years. He is believed to be living in Cuba.

Eugene K. Palmer (born April 4, 1939) is an American fugitive wanted for allegedly killing his daughter-in-law, Tammy Palmer (née Pannirello), in Stony Point, New York, on September 24, 2012. On May 29, 2019, he was named by the FBI as the 523rd fugitive to be placed on its Ten Most Wanted list. On July 20, 2022, he was removed from the FBI's Most Wanted Fugitives List. Despite his removal from the Top Ten List, he remains a highly wanted fugitive, and has an international Interpol warrant issued against him.
