The Warriors is a 1979 American action thriller film directed by Walter Hill and based on Sol Yurick's 1965 novel of the same name.
 This novel was, in turn, based on Xenophon's "Anabasis".
 The story centers on a New York City gang who must make an urban journey of 30 mile , from the north end of The Bronx to their home turf in southern Brooklyn, after they are framed for the murder of a respected gang leader.
 It was released in the United States on February 9, 1979.
The Shankill Butchers was an Ulster loyalist gang—many of whom were members of the Ulster Volunteer Force (UVF)—that was active between 1975 and 1982 in Belfast, Northern Ireland.
 It was based in the Shankill area and was responsible for the deaths of at least 23 people, most of whom were killed in sectarian attacks.
 The gang was notorious for kidnapping and murdering random Catholic and suspected Catholic civilians; each was beaten ferociously and had his throat hacked with a butcher's knife.
 Some were also tortured and attacked with a hatchet.
 The gang also killed six Ulster Protestants over personal disputes, and two other Protestants mistaken for Catholics.
 Most of the gang were eventually caught and, in February 1979, received the longest combined prison sentences in United Kingdom legal history.
 However, gang leader Lenny Murphy and his two chief "lieutenants" escaped prosecution.
 Murphy was killed in November 1982 by the Provisional IRA, likely acting with loyalist paramilitaries who perceived him as a threat.
 The Butchers brought a new level of paramilitary violence to a country already hardened by death and destruction.
 The judge who oversaw the 1979 trial described their crimes as "a lasting monument to blind sectarian bigotry".
Jack Powers (John Power) (1827 – November 1860) was an Irish born gambler, outlaw, highway-robber, gang leader, and murderer in southern and central California during the Gold Rush era.
 For a time in the 1850s, robberies and murders committed by his group of bandits made the stretch of El Camino Real between San Luis Obispo and Santa Barbara the most dangerous route in the state, and he and his gang had almost complete control of the small city of Santa Barbara.
 He was eventually driven out of town, but only after intimidating and defeating the sheriff and a posse of 200.
 He eventually fled the area, and after a brief career running a ranch in the Mexican state of Sonora, he was murdered in a fight over a woman, and his body was fed to a pen of starving pigs.

 A year later he was arrested in Boston for robbing a silk house owned by Scott & Co. and sentenced to 12 years imprisonment.
 It was while in prison that he discovered that eating common soap could produce the effect of ill health.
 His sudden and unexplainable weight loss and other symptoms baffled the prison doctors and he was able to fool officials that he was dying and received a pardon.
