the cause of death as suicide, but Majid's son appears at Georges's workplace to confront him. Believing the son is responsible for the tapes, Georges threatens him to cease surveillance, but the son replies he was not involved with the tapes and wanted to know how Georges felt about being responsible for a death. Later, Majid's son converses with Pierrot after school. Production Historical background A basis for the story was the massacre that took place in Paris on 17 October 1961, referenced by the character Georges: During the Algerian War, the National Liberation Front responded to the French right's attacks on France's Arabs, and as many as 200 protesters in Paris may have been shot or drowned in the Seine River. Maurice Papon was prefect of the Paris police, and previously served Vichy France; a book about Vichy is visible on Georges's shelf. In the aftermath of the massacre, the French government suppressed many of the facts by restricting police archives and delaying and cancelling public investigations, until allowing three historians to review the archives in 1998. The media reported three deaths in 1961; the massacre was not revisited until 1997 when Papon went to trial for his Vichy record. While planning the production of Caché, Haneke learned about the massacre, and how information about it was withheld for years, after seeing a television documentary on Arte. He remarked, given France's free press, "I was totally shocked that I had never heard of this event before". He decided to work it into his story. Development Haneke began writing the screenplay by September 2001. He described a starting point: "I had been toying with the idea of writing a script in which someone is confronted with his guilt for something he did in childhood". In planning the film, he chose the thriller genre as a model but intended the true point to be an exploration of guilt; he deliberately left the question of who sent the tapes ambiguous: Haneke also left it ambiguous whether the young Georges's claim that Majid coughed blood was a lie, but said he viewed the depiction of Majid menacing Georges with an ax as a mere nightmare. While the Paris massacre inspired the plot, Haneke said the story was not about a "French problem" as something unusual, remarking, "This film was made in France, but I could have shot it with very few adjustments within
