his position as the city's chief operating officer. Valarie J. McCall, who had previously served as Clerk of City Council, was appointed chief of government affairs. Shortly after his inauguration, Jackson began working with the Cleveland Police Department. He introduced a new use of force policy that clearly states what previous versions only implied: "Excessive force shall not be tolerated." Jackson has restored the Cleveland Police Aviation Unit (helicopters) and the Cleveland Police Mounted Unit (horses). He is a member of the Mayors Against Illegal Guns Coalition, a bi-partisan group with a stated goal of "making the public safer by getting illegal guns off the streets." The Coalition was co-chaired by Boston Mayor Thomas Menino and New York City Mayor Michael Bloomberg. Residency laws On January 18, 2008, the Ohio House of Representatives passed a bill to eliminate residency rules passed by local voters. This included the amendment to the Cleveland municipal charter that restricted city workers from living outside the city, approved by voters in 1982. In response, Mayor Jackson and law director Robert Triozzi threatened to take the issue to court. Jackson contended that if the city's residency restrictions are overturned, Cleveland would suffer the ill effects of city workers fleeing the city, and its related effects on the economy and city safety. "This is about the issue of home rule", Jackson said at a City Hall news conference. "They are attempting to usurp our constitutional rights, and we are defending our rights". He threatened to fire any city worker who moved out of their district of employment. The Cleveland Fire Fighters Association Local 93 and four individual union members filed a complaint on January 30 with the 8th Ohio District Court of Appeals to block any actions that Jackson, Triozzi, or the city might take on the matter. On June 10, 2009, the Supreme Court of Ohio struck down the residency requirements of Cleveland and several dozen other Ohio communities in the case of Lima v. State of Ohio.
