Nyasaland: a million Africans without a death-registration system
British colonial administration of Nyasaland
The 1913-1914 report listed 26 European births and seven deaths. On the same page the administration admitted that no organization existed to register African births and deaths. The African population was estimated at 1,065,119. Colonial authorities counted births and deaths in the small European community but had created no such system for more than a million Africans. By then, civil registration had operated in England and Wales, in the imperial metropole, since 1837.

Sierra Leone: Africans excluded from compulsory registration
British colonial administration of Sierra Leone
In the Sierra Leone Protectorate birth and death registration was compulsory for other residents but optional for indigenous Africans. In 1931 a British minister told Parliament that no birth or death figures were available for the Protectorate. A territory with more than 1.4 million Africans in the 1921 census remained under an administration imposing racially unequal registration requirements.

Japan: orders to burn evidence of war crimes
Imperial General Headquarters and Japanese military ministries
After announcing surrender, Japanese military leaders ordered secret documents destroyed, including evidence of crimes against prisoners of war. The orders themselves were to be burned, with implementation reported only by secure telephone. Military and civilian agencies destroyed archives before Allied troops arrived. NARA cites a Japanese military archive director estimating that up to 70% of the army's wartime records were burned or otherwise destroyed. The destruction deprived investigators of evidence of the empire's crimes.

Thousands of men, women and children died in experiments at Pingfan and other sites of Japan's biological warfare programme. US authorities collected evidence, then shielded Shiro Ishii and his colleagues from prosecution to obtain the experiment results and prevent a public scandal. Before Soviet interrogations, US officials instructed the Japanese specialists what answers to give. Correspondence documenting protection of programme participants and efforts to discourage prosecution survives in US government archives.
