In January 1955 Harry Nkumbula, President of the Northern Rhodesia African National Congress, and Kenneth Kaunda, the Secretary General, were each sentenced to two months imprisonment for possession of prohibited literature supplied by the Communist Party of Great Britain and other bodies. That same month a flat was broken into in Kitwe. An impression of the ball of a foot was found on the kitchen windowsill and lifted. Foot impressions were taken from 60 Africans employed locally and the burglar thus identified. He was put on an identification parade and recognised by a miner who had accosted him carrying a bundle on the morning of the crime and from whom he had run away. Northern Rhodesia Police Standing Orders required all identification parades to be photographed, some thirty years before the Code of Practice for the Identification of Persons Suspected of Offences, made under the Police and Criminal Evidence Act 1984 required a similar procedure in England and Wales. An African set fire to two huts and wounded a boy with an arrow. An African constable sent to arrest him found the man had acquired a muzzle loading gun. Though unarmed the constable gave chase only to be shot and seriously wounded. The accused successfully hid in the bush for many weeks until one morning he was found outside Kalulushi police station, sitting at the base of the flagpole with his arms clasped round it. This was probably the last instance of an offender giving himself up in this way which since the Early Days had been thought to give protection to an offender. Since it removed all question of force being necessary to effect an arrest the belief cannot be said to have been unfounded.  26 July 1956 saw the first of a series of strikes by African mineworkers on the Copperbelt, accompanied by violence and intimidation. When railway workers joined in and a General Strike was threatened a State of Emergency was declared in the Western Province. 77 activists were detained. Troops were called out and detachments of the BSAP and Nyasaland Police arrived to assist in the restoration of order which was complete by 24 September. In Barotseland towards the end of 1956 two missing African women were found shot in the back. Two brothers were arrested and stated that they had been hired by the deceased's relatives to carry out the killings as the women were believed to be Witches responsible for deaths in their villages. Witchcraft paraphernalia was found in the accused's dwellings and a "Kalalozi gun" recovered. Such guns had originally been made of bone. A "miloyi" or witchdoctor would point his gun at the sun and later at his victim who was supposed to die that night leaving no trace of the cause of death.
