In 2006 , McCarthy left his position with the New York Police Department to take over the Police Department of Newark , New Jersey . He was chosen for this role by Mayor Cory Booker , and appeared with Booker in the documentary series '' Brick City '' . McCarthy presided over a sharp reduction in crime during his tenure in Booker 's administration in Newark with homicides declining 28 percent , shootings declining 46 percent , and overall crime declining 21 percent . . ( During the 2020 Democratic Primary debates , Vice-President Biden nick-named McCarthy as " Giuliani 's guy " in an attack towards Senator Booker . ) McCarthy was hired by Mayor Rahm Emanuel to take over the Chicago Police Department shortly after Emanuel 's election in early 2011 . McCarthy was the City of Chicago 's highest paid public employee , earning an annual salary of over $ 260,000 . The number of crimes and murders in Chicago declined during his tenure ( with murders declining from 525 in 2011 to 505 in 2012 to 415 in 2013 ) . In an investigative article by '' Chicago '' Magazine reporters David Bernstein and Noah Isackson , it was asserted that the decline was in part due to the unjustified re-categorization of murders as undetermined and then if it is later determined to be a murder , tallying the total to the prior years ' statistics . McCarthy responded that the article is " patently false " and criticized its reliance on anonymous sources . A 2012 audit by the Chicago Inspector General determined that the Chicago Police Department had under-counted aggravated assault and aggravated battery victims by 25 percent by not following state guidelines by counting each incident rather than each victim . McCarthy attributed the error to the administration of the prior police superintendent , Jody Weis . On October 20 , 2014 , Laquan McDonald was murdered by Chicago Police Officer Jason Van Dyke . Laquan McDonald , a young black man , was 17 years old and was shot 16 times . A cover-up of this incident occurred , lasting 400 days , yet McCarthy had seen the video footage a few days after the murder occurred . When the video was released to the public following a court order , activists condemned police violence , the code of silence , and racism in the Chicago Police Department and called on Mayor Emanuel , State 's Attorney Anita Alvarez and Police Superintendent Garry McCarthy to resign . McCarthy did not resign , but was terminated by Rahm Emanuel
