A little research please.
Gun Control 						 					 				 				 					 						 							Since the early 1970s, Chicago and its suburban municipalities  have taken a national lead in enacting firearms control legislation.  Citizens' groups such as the Committee for Handgun Control, formed in  1973 and renamed Illinois Citizens for Handgun Control in 1982, have  worked together with city politicians and 							
police 							to pass some of the nation's toughest gun control laws. Mayor  Richard J. Daley was outspoken in his stand against gun rights  activists, testifying before U.S. House subcommittees on gun violence in  1972 and creating a special court to process gun crimes. In response to  rising gun violence by the end of the 1970s, several Chicago aldermen  began exploring the idea of a freeze on handgun registration. 						
 						 							In 1981 the suburb of 							
Morton Grove 							became the first municipality in the United States to ban the  sale, transportation, and ownership of handguns. When a federal judge  upheld the ban, the village attracted national attention. The National  Rifle Association began a campaign in many states to push for  legislation that would preempt gun regulations by municipal governments.  The campaign was unsuccessful in Illinois. In 1982, Mayor Jane Byrne  and the city council began to hold hearings on an ordinance proposed by  alderman Ed Burke banning the further sale and registration of handguns  in Chicago. Receiving strong support from Byrne and her allies, and  coming in the wake of the assassination attempts on President Reagan and  Pope John Paul II, the ordinance passed. All residents who purchased  and registered their handguns prior to January 1982 were allowed to keep  their weapons. Chicago became the first major city to enact a handgun  freeze in United States history.
