Vigilantism in the United States

Vigilantism in the United States of America is defined as acts which violate societal limits which are intended to defend and protect citizens from some form of attack or some form of harm.
In the new nation a citizen's arrest became known as a procedure, based on common law and protected by the United States Constitution when civilians arrest people whom they have either seen or suspect of doing things which are wrong.
The exact circumstances under which this type of arrest, also known as a detention, can be made varies widely from state to state.
When the British set up the American colonies, they established law enforcement along British lines. Population growth was slow and the law enforcement system worked. One important exception came in North Carolina, where rapid migration to the frontier established a new western region without a strong local government. There emerged the only major vigilante movement in colonial America. The term "vigilante" was not yet in use, and the acitivists called themselves "regulators." The poor farmers bitterly resented the overpaid corrupt local officials appointed by a distant elite, By 1768 the decentralized movement was highly popular in the backcountry. When two local leaders were arrested, 700 Regulators turned out to free them. In 1771 the governor led a force of a thousand men into the heart of the uprising, but Regulators led twice that number into the Battle of Alamance. The insurgents lacked leadership and strategy. They were quickly routed with nine Regulators dead. Seven of the leaders were executed and others fled the state. When the American Revolution broke out four years later, North Carolina's elite supported the Patriot cause, while the Regulator districts were much more likely to be neutral or pro-British.
The San Francisco Committee of Vigilance was a vigilante group formed in 1851 and reorganized in 1856 in response to rampant crime and corruption in San Francisco, California. The need for extralegal intervention was apparent with the explosive population growth following the discovery of gold in 1848. The small town of about 900 individuals grew to a booming city of over 20,000 very rapidly. This growth in population overwhelmed the small law enforcement system. The boss-controlled Democratic Party machine was dominant, and used Irish Catholic men to manipulate the precinct vote totals. The opposition Know Nothing movement represented the Protestant businessmen, and they formed the vigilance movement to counter the Democratic machine. The vigilantes hanged eight people and forced several elected officials to resign. The Committee of Vigilance formally relinquished power after three months, but its retired leaders ran the new Republican Party and controlled local politics for the next decade.
The Night Riders was the militant, terrorist faction of tobacco farmers during a popular resistance to the monopolistic practices of the American Tobacco Company (ATC) of James B. Duke. On September 24, 1904, the tobacco planters of western Kentucky and the neighboring counties of West Tennessee formed the Dark Fired Tobacco District, or Black Patch District Planters' Protective Association of Kentucky and Tennessee (called "the Association" or PPA). It urged farmers to boycott the ATC and refuse to sell at the ruinously low prices being offered in a quasi-monopoly market.
Groups of a more militant faction of farmers, trained and led by Dr. David A. Amoss of Caldwell County, Kentucky, resorted to terrorism—most notably, the lynching of the Walker family and the lynching of Captain Quentin Rankin and the kidnapping of Colonel R. Z. Taylor. Becoming known as the Night Riders, due to their night-time activities, they also targeted and destroyed the tobacco warehouses of the ATC. Their largest raid of this type was their occupation and attack on areas of Hopkinsville, Kentucky, in 1907.
