In 1953 Congress passed the District Government Reorganization Act. It formally abolished the rank and title of Major and Superintendent and replaced it with the position of Chief of Police. Murray would be the last Major and Superintendent and the first Chief of Police of the MPD. Murray's reforms and efforts improved the image of the department which expanded to 3,000 officers. He and the MPD earned public accolades for their handling of the Transit strikes in the hot summers of 1955 and 1956, the March on Washington, and the funeral of JFK. One of his final major acts would be to fully integrate assignments. Specific assignments and beats would no longer be given by only white officers or only black officers. Although it did not eliminate racist tensions and discrimination, it moved the department forward towards racial equality.
