  Passage: "Person of Interest" is an American science fiction crime drama television series created for CBS by Jonathan Nolan, who serves as an executive producer alongside J.J. Abrams, Bryan Burk, Chris Fisher, Greg Plageman, and Denise Thé.  The series stars Jim Caviezel as John Reese, a former CIA agent who is presumed dead.  He is approached by a mysterious billionaire named Harold Finch (Michael Emerson) who is trying to prevent violent crimes before they happen by using an advanced surveillance system dubbed "The Machine" that provides the SSN of a POI (person of interest) who will be involved in an imminent lethal crime as either a perpetrator or a victim.  Their unique brand of vigilante justice attracts the attention of two NYPD officers, Joss Carter (Taraji P. Henson) and Lionel Fusco (Kevin Chapman), whom Reese uses to his advantage as he investigates the POI.  Reese and Finch are later aided by Samantha "Root" Groves (Amy Acker), a highly intelligent computer hacker and contract killer whom the Machine later identifies as its "analog interface", and Sameen Shaw (Sarah Shahi), a former ISA assassin who unknowingly dealt with the "relevant" numbers found by the Machine.  During the course of the series, episodes of "Person of Interest " aired over seasons.
  Title: John F. Kennedy assassination Dictabelt recording
  Passage: The John F. Kennedy assassination Dictabelt recording was a recording from a motorcycle police officer's radio microphone stuck in the open position that became a key piece of evidence cited by the House Select Committee on Assassinations (HSCA) in their conclusion that there was a conspiracy behind the assassination of John F. Kennedy on November 22, 1963.  Made on a common Dictaphone dictation machine that recorded sounds in grooves pressed into a thin vinyl-plastic belt, the recording gained prominence among Kennedy assassination conspiracy theorists from 1978, in which the HSCA used it to conclude that there was a "high probability" that Lee Harvey Oswald did not act alone and that the Kennedy assassination was the result of a conspiracy.  Later scientific examination discredited this interpretation of the evidence.

  Title: Jack Shephard
  Passage: Dr. Jack Shephard is a fictional character and the main protagonist of the ABC television series "Lost", played by Matthew Fox.  "Lost" follows the journey of the survivors of Oceanic Airlines flight 815 on a mysterious island and their attempts to survive and escape, slowly uncovering more of the much broader island history they are a part of.  The character was originally conceived by creator J. J. Abrams, though the direction of storylines owes more to co-creator Damon Lindelof and fellow showrunner Carlton Cuse.  J.J. Abrams, the creator of "Lost", once told "Entertainment Weekly", "Jack Shephard may be the greatest leader in any television series."  Actor Matthew Fox would have some influence on the character during the course of the series' production.  For example, Fox's own tattoos were incorporated into the character's backstory.
