Chicago's top cop told reporters Monday that the failure to jail repeat offenders is to the blame for the city's out-of-control gun violence.  Chris Irvine at Fox News reports that Police Superintendent Eddie Johnson, who has been calling for tougher punishment for repeat gun offenders, spoke out on Monday after the city's second bloodiest weekend of the year, with 58 shootings leaving seven dead.  The violence has continued even after the city deployed and additional 600 officers to high crime neighborhoods.  Apparently, no gathering is off limits for gang shootings, including a back-to-school peace rally at a playground Saturday night, where three people were shot.  Chicago police are under one of the most restrictive consent decrees in the country, signed off by Mayor Rahm Emanuel to quell "black lives matter" protests over police shootings of black males and Obama Justice Department claims that police used racial profiling to target minorities, as reported last year by the Los Angeles Times.
