Question: Manhunt: The Search for Bin Laden premiered on HBO on May 1, 2013, two years after the death of which founder and head of the Islamist group Al-Qaeda?
Context: The death of Osama bin Laden gave rise to various conspiracy theories, hoaxes, and rumors.  These include the ideas that bin Laden had been dead for years, or is still alive.  Doubts about bin Laden's death were fueled by the U.S. military's supposed disposal of his body at sea, the decision to not release any photographic or DNA evidence of bin Laden's death to the public, the contradicting accounts of the incident (with the official story on the raid appearing to change or directly contradict previous assertions), and the 25-minute blackout during the raid on bin Laden's compound during which a live feed from cameras mounted on the helmets of the U.S. special forces was cut off. Manhunt: The Search for Bin Laden is a 2013 documentary film directed by Greg Barker that explores the Central Intelligence Agency's investigation of Osama bin Laden, starting from 1995 until his death in 2011.  It premiered on HBO on May 1, 2013, two years after the mission that killed bin Laden.  The documentary features narratives by many of the CIA analysts and operatives who worked over a decade to understand and track bin Laden, and includes archival film footage from across Washington, D.C., Pakistan, Saudi Arabia and elsewhere in the Middle East.  It also features extensive and rarely seen footage of Al-Qaeda training and propaganda videos, including video suicide notes from various terrorists who later worked as suicide bombers. Sa'ad bin Osama bin Muhammad bin 'Awad bin Laden (Arabic: سعد بن أسامة بن محمد بن عوض بن لادن‎ ‎ ; 1979 – July 2009), better known as Saad bin Laden, was one of Osama bin Laden's sons.  He continued in his father's footsteps by occupying a position within Al-Qaeda, and was being groomed to be his heir apparent.  He was killed in an American drone strike in 2009. The bin Laden family (Arabic: بن لادن‎ ‎ , "bin Lādin"), also spelled bin Ladin, is a wealthy family intimately connected with the innermost circles of the Saudi royal family.  The family was thrown into the media spotlight through the activities of one of its members, Osama bin Laden, the former head of al-Qaeda.  The financial interests of the bin Laden family are represented by the Saudi Binladin Group, a global oil and equity management conglomerate grossing $2 billion annually, and the largest construction firm in the world, with offices in London, Dubai and Geneva. Nasser al-Bahri (1972 – December 26, 2015), also known by his "kunya" or "nom de guerre" as Abu Jandal – "father of death", was a member of al-Qaeda in Afghanistan from 1996 to 2000.  He gave his bayat (secret oath of allegiance) to Osama bin Laden in 1998, an experience he describes in detail in his memoir.  He was in al-Qaeda for four years, first as one of bin Laden's twelve bodyguards, and then as head of Osama bin Laden's security detail.  A citizen of Yemen born in Saudi Arabia, Al-Bahri was radicalized in his teens by dissident Saudi Ulemas and participated in clandestine political activities which were funded in part by people trafficking.  Having determined to become a jihadist he went first to Bosnia and then, briefly, to Somalia before arriving in Afghanistan in 1996 in the hope of joining Al-Qaeda, which he soon did.  After four years, al-Bahri became "disillusioned", largely because bin Laden consolidated al-Qaeda's relationship with the Taliban by giving his bayat to its leader, Mullah Omar, but also because he had married and become a father. Osama bin Laden authored two fatāwā in the late 1990s.  The first was published in August 1996 and the second in February 1998.  At the time, bin Laden was not a wanted man in any country except his native Saudi Arabia, and was not yet known as the leader of the international terrorist organization al-Qaeda.  Therefore, these fatāwā received relatively little attention until after the August 1998 United States embassy bombings, for which bin Laden was indicted.  The indictment mentions the first fatwā, and claims that Khalid al-Fawwaz, of bin Laden's Advice and Reformation Committee in London, participated in its communication to the press. Adam Yahiye Gadahn (Arabic: آدم يحيى غدن‎ ‎ , "Ādam Yaḥyā Ghadan"; born Adam Pearlman; September 1, 1978 – January 19, 2015) was an American senior operative, cultural interpreter, spokesman and media advisor for the Islamist group al-Qaeda.  Since 2004, he had appeared in a number of videos produced by al-Qaeda as "Azzam the American" ('Azzām al-Amrīki, عزام الأمريكي, sometimes transcribed as Ezzam Al-Amerikee).  Gadahn, who converted to Islam from Christianity in 1995 at a California mosque, was described as "homegrown," meaning that he had converted to a religion he believed in so firmly that he was willing to harm his country of origin.  American intelligence officials allege that he inspired the 2007 Osama bin Laden video. Anwar al-Awlaki (also spelled al-Aulaqi, al-Awlaqi; Arabic: أنور العولقي‎ ‎ "Anwar al-‘Awlaqī"; April 21, 1971 – September 30, 2011) was an American and Yemeni imam and Islamic lecturer.  U.S. government officials allege that, in his position as a senior recruiter and motivator, he was centrally involved in planning terrorist operations for the Islamist militant group al-Qaeda, and he became the first United States citizen to be targeted and killed by a U.S. drone strike.  President Barack Obama ordered the strike.  His son, Abdulrahman al-Awlaki (a 16-year-old U.S. citizen), was killed in a U.S. drone strike two weeks later.  On January 29, 2017, Al-Awlaki's 8-year-old daughter, Nawar Al-Awlaki, was killed in a U.S. commando attack in Yemen which was ordered by Obama's successor, Donald Trump.  With a blog, a Facebook page, the al-Qaeda magazine "Inspire", and many YouTube videos, al-Awlaki was described by Saudi news station Al Arabiya as the "bin Laden of the Internet".  After a request from the U.S. Congress, in November 2010 Google removed many of al-Awlaki's videos from its websites.  According to "The New York Times", al-Awlaki's public statements and videos have been more influential in inspiring acts of terrorism in the wake of his assassination than before his death. Osama bin Laden, the founder and head of the Islamist group Al-Qaeda, was killed in Pakistan on May 2, 2011, shortly after 1:00 am PKT (20:00 UTC, May 1) by United States Navy SEALs of the U.S. Naval Special Warfare Development Group (also known as DEVGRU or SEAL Team Six).  The operation, code-named Operation Neptune Spear, was carried out in a CIA-led operation, with Joint Special Operations Command, commonly known as JSOC, coordinating the Special Mission Units involved in the raid.  In addition to SEAL Team Six, participating units under JSOC included the 160th Special Operations Aviation Regiment (Airborne), aka "Night Stalkers," and operators from the CIA's Special Activities Division, which recruits heavily from former JSOC Special Mission Units.  The operation ended a nearly 10-year search for bin Laden, following his role in the September 11, 2001 attacks on the US. The 2007 Osama bin Laden video originally appeared in a banner ad on an Islamic militant website regularly used by al-Qaeda on September 6, 2007.  The ad carried a picture of bin Laden and the logo of al-Qaeda's media production company As-Sahab.  An accompanying translated message read: "Soon, with the permission of God, a new visual tape, the Sheikh, the Lion, Osama bin Laden.  May God protect him."
