I am not sure what this thread is supposed to either demonstrate or suggest. The handgun ban ended in Chicago in 2010. Homicides in Chicago consistently dropped from 1990-2011 (with three small outliers); in 2012, homicides have risen dramatically as compared to the totals from the previous eight years (with one outlier). Yet, the 500 is still historically on the low end for Chicago. If, however, the 2012 rate is indicative of a new upward trend, then citing strict gun laws is the last thing that is helpful to the discussion, since the gun laws in Chicago are more lenient than they were in recent years.
I am not an advocate of gun control; however, using Chicago to argue anything is asinine.
