Explanation:

President Lyndon B. Johnson created a high commission to investigate the assasination of his predecessor John F. Kennedy in Dallas, Texas, on November 22, 1963. It was presided by Chief Justice Earl Warren. After a year of investigation, the body concluded that Lee Harvey Oswald had acted alone to shoot Kennedy, and that there were no domestic or foreign conspiracies. After Jack Ruby fatally wounded Oswald, he said he had acted on his own out of rage for Kennedy´s assasination. Oswald´s motives were never known.
