Problem: Background: Bullet for My Valentine, often abbreviated as BFMV, are a Welsh heavy metal band from Bridgend, formed in 1998. The band is currently composed of Matthew Tuck (lead vocals, rhythm guitar), Michael Paget (lead guitar, backing vocals), Jason Bowld (drums) and Jamie Mathias (bass guitar). Former members include Michael Thomas, Jason James and Nick Crandle; the latter were on bass. They were formed under the name Jeff Killed John and started their music career by covering songs by Metallica and Nirvana.
Context: On 28 January 2011, Michael Paget stated that the group had already drawn proportions for the next studio album and will sound a lot like Fever. He followed-along with stating that the band plans to have the songs for it written within 2011 and will begin recording the album by the end of the year. A couple tracks left from the Fever sessions might be re-done, re-arranged and re-recorded for the new record. The band played at Uproar Festival 2011, after which they began writing material for a fourth studio album.  On 7 October, RCA Music Group announced it was disbanding Jive Records along with Arista Records and J Records. With the shutdown, the band (and all other artists previously signed to these three labels) will release their future material (including their next studio album) on the RCA Records brand. Also in October, frontman Matt Tuck announced that he will be working on a new side project which he has described as "metal as fuck", influenced by bands such as Pantera and Slipknot. On 1 May 2012, it was revealed that the project will be called AxeWound, and will feature Liam Cormier, Mike Kingswood, Joe Copcutt and Jason Bowld. In May 2012, it was announced that Bullet for My Valentine would be playing at the South African music festival Oppikoppi, as well as a once-off gig in Cape Town alongside Seether and Enter Shikari. They were slated to play in the country for the Coke Zero Fest of 2009, but pulled out at the last minute to record Fever. It was confirmed on 6 August that the final recording session of the band's fourth studio record was complete, and that the album would be out sometime in late 2012. Later that month on the 17th, the second line-up for the Australian music festival Soundwave was announced, containing Bullet for My Valentine.  Bullet for My Valentine released the track "Temper Temper" on 25 November in the UK and 30 October worldwide across all digital providers. The song was debuted live by the band on Monday 22 October at BBC Radio 1's Rock Week where they performed at Maida Vale studios. It was announced the day prior to the performance that the band's fourth studio album would also be named Temper Temper. The release date was confirmed to be the 12 February 2013.

Background: 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.
Context: 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."
Question: why is he incarcerated?
Answer:
he shot John Lennon.
