CHICAGO -- Chicago Police Supt. Eddie Johnson said the violence in Chicago won't let up until gun laws change.
Johnson repeated that view at a press conference Tuesday announcing Labor Day weekend crime statistics.
Johnson said there are too many repeat gun crime offenders on the streets and too many people with guns who aren't afraid to use them, regardless of the consequences.
Chicago's murder rate topped 500 over holiday, bringing the total number of homicides in Chicago to its highest in two decades.
Chicago has more murders than New York and Los Angeles combined this year, according to police figures.
Johnson said Chicago's murder numbers would sink below those of the bigger cities if Chicago had the same gun laws as the two.
