An Aurora-size massacre occurs EVERY 10 days in the City of Chicago. But there are no flags at half staff, 24/7 national media coverage, national outrage, or Presidential visits.
No, the gun-grabbers cannot explain away their oppressive gun laws there with the inverse relationship of their oppressive and unconstitutional firearms laws to gun deaths. It might start an objective discussion of the real reasons for the deaths. It might even splatter some dirt on Chicago politicians in high places in the nation.
Chicago is the poster child for the old "When guns are outlawed only outlaws will have guns" motto.
