Calling gun control the “weak link” in Chicago's public safety chain, Mayor Rahm Emanuel renewed a pitch for stiffer sentencing, background checks before gun purchases, and a revised and strengthened assault weapons ban, reports the Chicago Sun-Times. The mayor's political call to arms follows a Fourth of July weekend bloodbath that saw 38 shooting incidents from Wednesday evening through Sunday afternoon, including 10 homicides. It came hours before the legislature overrode Gov. Pat Quinn's rewrite of a bill legalizing the carrying of concealed weapons. Illinois will no longer be the only state that does not permit gun owners to carry their weapons in public places. Quinn's now-rejected tweaks would have placed limits on the number of guns and the amount of ammunition gun owners could carry and banned concealed carry in public places where alcohol is served. The mayor said there were more than 100 cases during the first six months of this year where either the victims or perpetrators of gun crimes would have been in prison if stiffer sentences had been in place.
