There is mention of racial discrimination in the speech of Martine Luther King Jr in USA. He is referring to the segregation policies adopted by the Whites towards the Coloured people. He aspires for a country where there will be security for all; where racial abuse will not occur; and where everyone will be treated as equal irrespective of the colour of their skin. This speech and the incident at the Mexico Olympics are both part of a movement that wanted to highlight the plight of the African-American people.
