Umm...its not. Has nothing to do with it.
Crime and murder in NY went down when Juliannie cracked down HARD on gangs and thugs a few years back. Chicago under Daily was too soft to put that pressure on the bad guys.
Result = crime still high in Chicago because they refuse to be hard on the really bad illegal gun toting criminals.
Although i just read that Rhom is introducing some new laws that increase jail time and fines for breaking the hand gun laws. That might acutally work, because if a little slap and time is all you get for toting around an illegal registered 30 round glock, then they are going to still do it time after time.
It's not that hard to be better about all of this, it's just that Politics gets in the way!
