Some context: Michael Andrew McKagan grew up in Seattle's largely working-class University District, the youngest of eight children born to Marie and Elmer "Mac" McKagan. He has been called "Duff" since toddlerhood, to which he once referred as "an Irish thing". Following his parents' divorce, his mother supported the family by taking a job as a medical stenographer. He was taught how to play bass by his brother Bruce, further developing his skills by playing along with the albums 1999 by Prince and Damaged by Black Flag.
In 1979, at the age of 15, McKagan formed the punk band the Vains, in which he played bass; they released the single "School Jerks" in 1980. During this time, he also played guitar in the punk band the Living, which opened shows for Husker Du and D.O.A., which developed a devoted following.  In 1980, McKagan joined the pop-punk band the Fastbacks as their drummer. He appeared on their 1981 debut single "It's Your Birthday", which was issued on guitarist Kurt Bloch's label No Threes Records, and on the song "Someone Else's Room", which was included on the Seattle Syndrome Volume One compilation album, also released in 1981.  In 1982, McKagan became the drummer for the hardcore punk band The Fartz, with whom he recorded several demos, five of which were included on their 1990 album You, We See You Crawling. After several line-up changes, The Fartz evolved into the post-punk band 10 Minute Warning, for which McKagan played guitar.  In 1983, McKagan moved to Los Angeles, California, with one of his brothers where he found work as an appetizer server at a Black Angus restaurant in Northridge. Answering an ad for a bass guitarist in a local newspaper, he met guitarist Slash and drummer Steven Adler, with whom he formed the short-lived band Road Crew. They auditioned a number of singers, including one-time Black Flag vocalist Ron Reyes, and worked on material that included the main riff of what would become the Guns N' Roses song "Rocket Queen". Slash eventually disbanded the group due to them not being able to find a singer, as well as Adler's lack of work ethic compared to himself and McKagan.

Some context: Chapter 27 is a 2007 biographical drama film depicting the murder of John Lennon by Mark David Chapman. It was written and directed by Jarrett Schaefer, based on the book Let Me Take You Down by Jack Jones, produced by Robert Salerno, and stars Jared Leto as Chapman. The film takes place in December 1980, and is intended to be an exploration of Chapman's psyche. Its title is a reference to J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and suggests a continuation of the book.
The real Mark David Chapman is currently incarcerated at Wende Correctional Facility, on a guilty plea. Aside from two interviews with Larry King and Barbara Walters, both in 1992, he has not spoken with the media. However, Chapman did reveal the mechanics of his unraveling during those three days in New York City to journalist Jack Jones. The interviews were published in 1992 as Let Me Take You Down: Inside the Mind of Mark David Chapman, a book of Chapman's recollections of his act of violence. Chapter 27 is based on this text. The title "Chapter 27" suggests a continuation of J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and which Chapman was carrying when he shot John Lennon. Chapman was obsessed with the book, to the point of attempting to model his life after its protagonist, Holden Caulfield.  According to the British music magazine Mojo, the title was also inspired by Chapter 27 of Robert Rosen's book Nowhere Man: The Final Days of John Lennon (2000). Rosen's book explores the numerological meaning of the number 27, "the triple 9", a number of profound importance to John Lennon. Lennon was deeply interested in numerology, particularly Cheiro's Book of Numbers, along with nine and all its multiples. It was Chapman's goal, according to Rosen, to write Chapter 27 "in Lennon's blood".  Like Chapman, Schaefer is a fan of both The Beatles and J.D. Salinger's novel The Catcher in the Rye, and said he began the script to try to understand "how someone could be inspired to kill anyone as a result of being exposed to this kind of beautiful art. It really bothered me, because Lennon and Salinger have always made me feel so much better, and so much less alone."

Some context: Alfred Charles Sharpton Jr. was born in the Brownsville neighborhood of Brooklyn, New York City, to Ada (nee Richards) and Alfred Charles Sharpton Sr. The family has some Cherokee roots. He preached his first sermon at the age of four and toured with gospel singer Mahalia Jackson. In 1963, Sharpton's father left his wife to have a relationship with Sharpton's half-sister.
Sharpton said in 1988 that he informed for the government in order to stem the flow of crack cocaine into black neighborhoods. He denied informing on civil rights leaders.  In 2002, HBO's Real Sports with Bryant Gumbel aired a 19-year-old FBI videotape of an undercover sting operation showing Sharpton with an undercover FBI agent posing as a Latin American businessman and a reputed Colombo crime family captain. During the discussion, the undercover agent offered Sharpton a 10% commission for arranging drug sales. On the videotape, Sharpton mostly nods and allows the FBI agent to do most of the talking. No drug deal was ever consummated, and no charges were brought against Sharpton as a result of the tape.  In April 2014, The Smoking Gun obtained documents indicating that Sharpton became an FBI informant in 1983 following Sharpton's role in a drug sting involving Colombo crime family captain Michael Franzese. Sharpton allegedly recorded incriminating conversations with Genovese and Gambino family mobsters, contributing to the indictments of several underworld figures. Sharpton is referred to in FBI documents as "CI-7."  Summarizing the evidence supporting that Sharpton was an active FBI informant in the 1980s, William Bastone, the Smoking Gun's founder, stated: "If he (Sharpton) didn't think he was an informant, the 'Genovese squad' of the FBI and NYPD officials sure knew him to be an informant. He was paid to be an informant, he carried a briefcase with a recording device in it, and he made surreptitious tape recordings of a Gambino crime family member 10 separate times as an informant. He did it at the direction of the FBI, he was prepped by the FBI, was handed the briefcase by the FBI and was debriefed after the meetings. That's an informant." Sharpton disputes portions of the allegations.  Sharpton is alleged to have secretly recorded conversations with black activists in the 1980s regarding Joanne Chesimard (Assata Shakur) and other underground black militants. Veteran activist Ahmed Obafemi told the New York Daily News that he had long suspected Sharpton of taping him with the bugged briefcase.
