Edited sentence: A subsequent siege of the building in the Olympic village lasted almost 18 hours.All Olympic events were briefly suspended but the International Olympic Committee president Avery Brundage decided that "the Games must go on" and they continued a day later.Another fact that came to light recently is the fact that most sniper didn't have adequate sniper rifles nor communications.Another fact that contributed to the outcome was that the committee that supervised all actions that day only one professional (Schreiber) and two politicians (Secretary of the Interior Genscher and another politician) made the decisions.During a failed rescue attempt at the military airport of Fürstenfeldbruck by ordinary policemen without adequate experience in hostage situations and under the incompetent supervision of munich police commissioner Manfred Schreiber all the Israeli hostages were killed by their captors and all but three of the terrorists were killed.It came to light that several (ordinary) police officers left their posts (after  a vote) in the waiting 727 jet without even trying to kill the leader and vice-leader of the terrorist cell which were supposed to be neutralized during the inspection of the getaway plane.It has to be mentioned that no none was disciplined or fired for the disastrous outcome of the failed attempt and subsequent killing of all hostages and one police officer.On 5 September Palestinian terrorists from the Black September group held 9 Israeli athletes hostage and killed 2 other athletes in their apartment.The ex-police commissioner is still unwilling to admit any wrongdoing in the disaster.The official report is still secret and insiders have leaked the 3800 pages to the sister of the killed jewish athlete Andre Spitzer.Those were all factors that contributed to the disastrous outcome
