been motivated by "ill-will or spite". In October 2003, South Africa's justice ministry announced that the five policemen would not be prosecuted because the statute of limitations had elapsed and there was insufficient evidence to secure a prosecution. Ideology The ideas of the Black Consciousness Movement were not developed solely by Biko, but through lengthy discussions with other black students who were rejecting white liberalism. Biko was influenced by his reading of authors like Frantz Fanon, Malcolm X, Léopold Sédar Senghor, James Cone, and Paulo Freire. The Martinique-born Fanon, in particular, has been cited as a profound influence over Biko's ideas about liberation. Biko's biographer Xolela Mangcu cautioned that it would be wrong to reduce Biko's thought to an interpretation of Fanon, and that the impact of "the political and intellectual history of the Eastern Cape" had to be appreciated too. Additional influences on Black Consciousness were the United States-based Black Power movement, and forms of Christianity like the activist-oriented black theology. Black Consciousness and empowerment Biko rejected the apartheid government's division of South Africa's population into "whites" and "non-whites," a distinction that was marked on signs and buildings throughout the country. Building on Fanon's work, Biko regarded "non-white" as a negative category, defining people in terms of an absence of whiteness. In response, Biko replaced "non-white" with the category "black," which he regarded as being neither derivative nor negative. He defined blackness as a "mental attitude" rather than a "matter of pigmentation", referring to "blacks" as "those who are by law or tradition politically, economically and socially discriminated against as a group in the South African society" and who identify "themselves as a unit in the struggle towards the realization of their aspirations". In this way, he and the Black Consciousness Movement used "black" in reference not only to Bantu-speaking Africans but also to Coloureds and Indians, who together made up almost 90% of South Africa's population in the 1970s. Biko was not a Marxist and believed that it was oppression based on race, rather than class, which would be the main political motivation for change in South Africa. He argued that those on the "white left" often promoted a class-based analysis as a "defence mechanism... primarily because they want to detach us from anything relating to race. In case it has a rebound effect on them because they are white". Biko saw white racism in South Africa as
