Context paragraphs:
The Human Centipede (First Sequence): The Human Centipede (First Sequence) is a 2009 Dutch horror film written, directed, and co-produced by Tom Six.  The film tells the story of a German surgeon who kidnaps three tourists and joins them surgically, mouth to anus, forming a "human centipede", a conjoined triplet.  It stars Dieter Laser as the creator of the centipede, Dr. Josef Heiter, with Ashley C. Williams, Ashlynn Yennie, and Akihiro Kitamura as his victims.  According to Six, the concept of the film arose from a joke he made with friends about punishing a child molester by stitching his mouth to the anus of a "fat truck driver".  Inspiration for the film also came from Nazi medical experiments carried out during World War II, such as the crimes of Josef Mengele at the Auschwitz concentration camp.

Yulia Drunina: Yulia Vladimirovna Drunina (Russian: Ю́лия Влади́мировна Дру́нина ; ] , May 10, 1924 – November 21, 1991) was a Soviet poet who wrote in the Russian language.

Josef Mengele: Josef Mengele (] ; 16 March 19117 February 1979) was a German "Schutzstaffel" (SS) officer and physician in Auschwitz concentration camp during World War II.  Mengele was a member of the team of doctors responsible for the selection of victims to be killed in the gas chambers and for performing deadly human experiments on prisoners.  Arrivals deemed able to work were admitted into the camp, and those deemed unfit for labor were immediately killed in the gas chambers.  Mengele left Auschwitz on 17 January 1945, shortly before the arrival of the liberating Red Army troops.  After the war, he fled to South America, where he evaded capture for the rest of his life.

World War II casualties of Poland: Approximately six million Polish citizens perished during World War II: about one fifth of the pre-war population.

Prosecution of gender-targeted crimes: Prosecution of gender-targeted crimes is the legal proceedings to prosecute crimes such as rape and domestic violence.  The earliest documented prosecution of gender-based/targeted crimes is from 1474 when Sir Peter von Hagenbach was convicted for rapes committed by his troops.  However, the trial was unsuccessful in indicting Sir von Hagenbach with the charge of rape because the war in which the rapes occurred was "undeclared" and thus the rapes were only considered illegal.  Gender-targeted crimes continued to be prosecuted, but it was not until after World War II when an international criminal tribunal- the International Military Tribunal for the Far East (Tokyo Tribunal)- were officers charged for being responsible of the gender-targeted crimes (particularly rape) and other crimes against humanity.  Despite the various rape charges, the Charter of the Tokyo Tribunal did not make references to rape, and rape was considered as subordinate to other war crimes.  This is also the situation for other tribunals that followed, but with the establishments of the International Criminal Tribunal for the former Yugoslavia (ICTY) and the International Criminal Tribunal for Rwanda (ICTR), there was more attention to the prosecution of gender-targeted crimes with each of the statutes explicitly referring to rape and other forms of gender-targeted violence.

Melody of Murder: The Melody of Murder, (Original Title: Mordets Melodi), is a 1944 Danish film noir directed by Bodil Ipsen and starring Gull-Maj Norin and Poul Reichhardt.  The dark tale revolves around a sexually ambiguous serial killer whose crimes are committed to a French cabaret song, and the police suspect a chanteuse who sings the same tune during her performances.  Produced during the German occupation of Denmark in World War II, the film was praised by critics for its "stylish cinematography, thematic intensity, and dark vision of Copenhagen;" and consider it one of the most influential Danish films of that period.

War crimes in occupied Poland during World War II: It's estimated that over six million Polish citizens, divided nearly equally between Christian and Jewish Poles, perished during World War II.  Most were civilians killed by the actions of Nazi Germany, the Soviet Union and their respective allies.  At the Nuremberg Tribunal, three categories of wartime criminality were established: waging a war of aggression, war crimes, and crimes against humanity.  These three core crimes of international law were set apart from other crimes, and for the first time since the end of the war categorised as violations of fundamental human values and norms.  They were committed in occupied Poland on a tremendous scale.

Definitions of Japanese war crimes: There are differences from one country to another regarding the definition of Japanese war crimes.  War crimes have been broadly defined as violations of the laws or customs of war, which include crimes against either enemy combatants or enemy non-combatants.  War crimes also included deliberate attacks on citizens and property of neutral states as they fall under the category of non-combatants, as at the attack on Pearl Harbor.  Military personnel from the Empire of Japan have been accused and/or convicted of committing many such acts during the period of Japanese imperialism from the late 19th to mid-20th centuries.  They have been accused of conducting a series of human rights abuses against civilians and prisoners of war (POWs) throughout east Asia and the western Pacific region.  These events reached their height during the Second Sino-Japanese War of 1937–45 and the Asian and Pacific campaigns of World War II (1941–45).
