william joseph `` bill '' bratton cbe -lrb- born october 6 , 1947 -rrb- is an american law enforcement officer and businessman , and the current new york city police commissioner , the second time he has held that position .
he has previously served as the commissioner of the boston police department -lrb- bpd -rrb- -lrb- 1993 -- 1994 -rrb- , new york city police department -lrb- nypd -rrb- commissioner -lrb- 1994 -- 1996 -rrb- , and chief of the los angeles police department -lrb- lapd -rrb- -lrb- 2002 -- 2009 -rrb- .
bratton began his police career at the boston police department before becoming police commissioner in new york city , where his zero-tolerance policy has been credited with reducing petty and violent crime .
he moved to the los angeles police department in 2002 reforming the police after the 1992 los angeles riots and crime was reduced .
bratton 's policing style is influenced by the broken windows theory , a criminological theory of the norm-setting and signalling effect of urban disorder and vandalism `` on additional '' crime and anti-social behavior .
he advocates having an ethnically diverse police force representative of the population , maintaining a strong relationship with the law-abiding population , tackling police corruption , being tough on gangs and having a strict no-tolerance of anti-social behavior .
bratton was approached by british prime minister david cameron to become the new metropolitan police commissioner in july 2011 , but this was blocked by the home office on the grounds the commissioner must be a british national with experience of english law .
bratton instead was offered an advisor role to the british government , which he accepted in august 2011 .
on december 5 , 2013 , new york city mayor bill de blasio announced that bratton would return to the post of police commissioner in new york city .
