Although it was passed uncut for UK cinemas in December 1971, British authorities considered the sexual violence in the film to be extreme. In March 1972, during the trial of a 14-year-old male accused of the manslaughter of a classmate, the prosecutor referred to "A Clockwork Orange", suggesting that the film had a macabre relevance to the case. The film was also linked to the murder of an elderly vagrant by a 16-year-old boy in Bletchley, Buckinghamshire, who pleaded guilty after telling police that friends had told him of the film "and the beating up of an old boy like this one". Roger Gray QC, for the defence, told the court that "the link between this crime and sensational literature, particularly "A Clockwork Orange", is established beyond reasonable doubt". The press also blamed the film for a rape in which the attackers sang "Singin' in the Rain" as "Singin' in the Rape". Christiane Kubrick, the director's wife, has said that the family received threats and had protesters outside their home.
