The total number of people shot in Chicago from Memorial Day through August 27 was 1,026 -- down 15 percent from the same time period last year, according to the Tribune.

Overall homicides during that same time period were down 27 percent.

The areas of the city where most of the shootings unfold are characterized not only by deteriorating neighborhoods, but also by a lack of quick, efficient emergency care.
