Boston stand with officers of the Boston Police Department Bratton returned to Boston in 1970 to start a police career in the
Boston Police Department (BPD), and was sworn in as an officer in October 1970. He was promoted to sergeant in July 1975. While serving as a Boston Police Officer, Bratton earned a Bachelor of Science in Public Service/Public Administration in 1975 from Boston State College (later absorbed by the University of Massachusetts-Boston). In his early police career, he served as the partner of
Francis Roache. Like Bratton, Roache also later served as Commissioner of the BPD. In October 1980, at the age of 32 and ten years after his appointment to the
BPD, Bratton was named as the youngest-ever Executive Superintendent of the Boston Police, the department's second highest post. He was dismissed as executive superintendent after he told a journalist that his goal was to be the Police Commissioner. He was reassigned to the position of Inspector of Bureaus, a
sinecure which was responsible for liaison with minority and
LGBTQ communities. He was later brought back into police headquarters to handle labor relations and
9-1-1 related issues. Between 1983 and 1986, Bratton was Chief of Police for the
Massachusetts Bay Transportation Authority, following which he became
Superintendent of the Massachusetts
Metropolitan District Commission Police. Bratton was Superintendent in Chief of the
Boston Police Department from 1992 until 1993, then he became that city's 34th Police Commissioner. He holds the Department's highest
award for valor.
New York City (first tenure) Bratton became the chief of the
New York City Transit Police in 1990. In 1994, Bratton was appointed the 38th Commissioner of the
New York City Police Department (NYPD) by Mayor
Rudy Giuliani. He cooperated with Giuliani in putting the controversial
broken windows theory into practice. He introduced the
CompStat system of tracking crimes in New York City. Critics have argued that CompStat has created perverse incentives for officers to allow crimes to go unreported, and has encouraged police brutality, citing that complaints by citizens that involved incidents where no arrest was made or summons was issued more than doubled during the Giuliani administration. Bratton resigned in 1996, while under investigation by the Corporation Counsel for the propriety of a book deal that he signed while in office as well as accepting multiple unauthorized trips from corporations and individuals. These offenses were generally considered minor. Front and center were alleged personal conflicts with Giuliani, partly due to Giuliani's opposition to some of Bratton's reforms and partly due to Giuliani's belief that Bratton was getting more credit for the reduction in crime than Giuliani. The experiences of Bratton and New York Deputy Police Commissioner
Jack Maple were used as the inspiration of the television series
The District.
Los Angeles , at
LA/Valley Pride in 2009 Bratton worked as a private consultant with
Kroll Associates, also known as LAPD's Independent Monitor, until his appointment by the
Mayor of Los Angeles James Hahn as the LAPD's 54th Chief of Police in October 2002. Bratton was one of three candidates recommended to Hahn by the Los Angeles Police Commission under Commission President
Rick J. Caruso. On June 19, 2007, the
Los Angeles Police Commission reappointed Bratton to a second five-year term, the first reappointment of an LAPD chief in almost twenty years. Bratton has been criticized for his extensive travel; in 2005, he was out of town for a full third of the year on both official and personal business. In March 2009, Councilman
Herb Wesson proposed an amendment to the City Charter, allowing Bratton to serve a third consecutive term as Police Chief. On September 11, 2009, he was awarded with the honorary title of
Commander of the Most Excellent Order of the British Empire by
Queen Elizabeth II "in recognition of his work to promote cooperation between US and UK police throughout his distinguished career". On August 12, 2011, Bratton said he was in talks with the
British government to become an adviser on controlling the violence that had
affected London the prior week. He said he received a phone call from U.K. Prime Minister
David Cameron, and that he would continue speaking with British officials to formalize an agreement. Bratton was approached by British Prime Minister
David Cameron to become the new
Metropolitan Police Commissioner in July 2011, but
Theresa May and the
Home Office said that the commissioner was required to be a British citizen. Bratton instead was offered an advisor role to the British government, which he accepted in August 2011.
New York City (second tenure) ; NYC Mayor
Bill de Blasio; U.S. Sec. of Homeland Security
Jeh Johnson; Bratton; and NYFD Commissioner
Daniel Nigro speak to media in 2015 On December 5, 2013, New York City mayor-elect
Bill de Blasio named Bratton as New York City's new Police Commissioner to replace
Raymond Kelly.
The New York Times reported that at Bratton's swearing in on January 2, 2014, the new Police Commissioner praised his predecessor
Raymond Kelly, but also signaled his intention to strike a more conciliatory tone with ordinary New Yorkers who had become disillusioned with policing in the city: "We will all work hard to identify why is it that so many in this city do not feel good about this department that has done so much to make them safe – what has it been about our activities that have made so many alienated?" He stepped down in 2016.
New Orleans Following the January 1, 2025
attack on Bourbon Street the New Orleans Police Department hired William Bratton to review the city's security plans and strengthen them against future threats. Bratton worked closely with New Orleans chief
Anne Kirkpatrick with funding provided by the New Orleans Police and Justice Foundation. ==Later career==
