Crystal City is an urban neighborhood in the southeastern corner of Arlington County, Virginia, approximately 5 miles (8.0 km) south of Downtown Washington, D.C. Due to its extensive integration of office buildings and residential high-rise buildings using underground corridors, travel between stores, offices, and residences, it is possible to travel much of the neighborhood without going above ground, making part of Crystal City an underground city.

Crystal City includes several aerospace manufacturing and defense industry companies, public sector consulting firms, government contractors, the U.S. Department of Labor, the U.S. Marshals Service, satellite offices for the Pentagon, and nonprofit organizations, including the International Foundation for Electoral Systems and the national headquarters for PBS.

Lewis Cass (October 9, 1782 – June 17, 1866) was a United States Army officer and politician. He represented Michigan in the United States Senate and served in the Cabinets of two U.S. Presidents, Andrew Jackson and James Buchanan. He was also the 1848 Democratic presidential nominee. A slave owner himself, he was a leading spokesman for the doctrine of popular sovereignty, which at the time held the idea that people in each U.S state should have the right to decide whether to permit slavery as a matter of states' rights.

Born in Exeter, New Hampshire, he attended Phillips Exeter Academy before establishing a legal practice in Zanesville, Ohio. After serving in the Ohio House of Representatives, he was appointed as a U.S. Marshal. Cass also joined the Freemasons and eventually co-founded the Grand Lodge of Michigan. He fought at the Battle of the Thames in the War of 1812 and was appointed to govern Michigan Territory in 1813. He negotiated treaties with American tribes to open land for American settlement as part of a belief in "manifest destiny" and led a survey expedition into the northwest part of the territory.

Margaret Garner (died 1858) was an enslaved African-American woman who killed her own daughter and intended to kill her other three children and herself rather than be forced back into slavery. Garner and her family had escaped enslavement in January 1856 by traveling across the frozen Ohio River to Cincinnati, but they were apprehended by U.S. Marshals acting under the Fugitive Slave Act of 1850. Garner's defense attorney, John Jolliffe, moved to have her tried for murder in Ohio, to be able to get a trial in a free state and to challenge the Fugitive Slave Law. Garner's story was the inspiration for the novel Beloved (1987) by Nobel Prize–winning author Toni Morrison and its subsequent adaptation into a film of the same name starring Oprah Winfrey (1998).

The Whiskey Rebellion (also known as the Whiskey Insurrection) was a violent tax protest in the United States beginning in 1791 and ending in 1794 during the presidency of George Washington. The so-called "whiskey tax" was the first tax imposed on a domestic product by the newly formed federal government. The "whiskey tax" became law in 1791, and was intended to generate revenue to pay the war debt incurred during the American Revolutionary War. Farmers of the western frontier were accustomed to distilling their surplus rye, barley, wheat, corn, or fermented grain mixtures to make whiskey. These farmers resisted the tax.

Throughout western Pennsylvania counties, protesters used violence and intimidation to prevent federal officials from collecting the tax. Resistance came to a climax in July 1794, when a US marshal arrived in western Pennsylvania to serve writs to distillers who had not paid the excise. The alarm was raised, and more than 500 armed men attacked the fortified home of tax inspector John Neville. Washington responded by sending peace commissioners to western Pennsylvania to negotiate with the rebels, while at the same time calling on governors to send a militia force to enforce the tax. Washington himself rode at the head of an army to suppress the insurgency, with 13,000 militiamen provided by the governors of Virginia, Maryland, New Jersey, and Pennsylvania. The leaders of the rebels all fled before the arrival of the army, and there was no confrontation. About 150 men were arrested, but only 20 held for trial in Philadelphia, and only two were convicted (eventually pardoned).

Newton Knight (November 10, 1829 – February 16, 1922) was an American farmer, soldier, and Southern Unionist in Mississippi, best known as the leader of the Knight Company, a band of Confederate Army deserters who resisted the Confederacy during the Civil War. Local legends tell of Knight and his men forming the "Free State of Jones" in the area in and around Jones County, Mississippi, at the height of the war. The nature and extent of the Knight Company's opposition to the Confederate government is disputed among historians. After the war, Knight joined the Republican Party and served in Mississippi's Reconstruction government as a deputy U.S. Marshal.

Knight has long been a controversial figure in the region, with people divided over his motives and actions. He and his allies developed a small mixed-race community in southeastern Mississippi. His interracial marriage with Rachel Knight was considered illegal, as Mississippi had banned interracial marriages before and after the war, except for a brief period during Reconstruction.

The United States Federal Witness Protection Program (WPP), also known as the Witness Security Program or WITSEC, is a witness protection program codified through 18 U.S. Code § 3521 and administered by the United States Department of Justice.

The program is operated by the United States Marshals Service and is designed to protect threatened witnesses and their family members before, during, and after a trial when those witnesses have an association with the federal government.
