In December 1951, Robert V. Murray became Major and Superintendent. He took the command of a demoralized department marred by embarrassments, corruption, and waning public support. During his 13 years as chief, Murray would be credited with making the most sweeping, and longest lasting changes in the MPD's history and is seen as bringing the department into the modern era of policing. One of his first acts was that he would make rounds of the various precincts, inspecting them and the officers where he promised his support. He developed a code of ethics for officers and created a new branch to investigate police corruption, named the Internal Investigations Division—this was a precursor to the Internal Affairs Division. Murray also made good on his promise to improve conditions for his department. By 1952 Murray had petitioned Congress to give his officers a ten percent raise, had turned the six-day work week into a five-day work week, and worked to have two officers per patrol car. He went on to improve the MPD's vehicle fleet, initiated the use of canines, radar, helicopters and experimented with hand held radios.
