Gun control in action.

(CNN) – A war among criminals rages on in America's third-largest city, with innocent residents caught in the crossfire. 

Over the holiday weekend, Chicago passed an ominous threshold: So far in 2016, 2,000 people have been victims of gun violence.

In all of last year, 2,988 people were victims of gun violence, according to records kept by The Chicago Tribune.

Over the Fourth of July weekend, four people were killed and 46 were injured in 42 shootings and a stabbing, according to a release from Chicago police. Last July 4 weekend, seven were killed and 40 wounded. 

Looking at all of 2016 — in every metric that matters in tracking gun violence — the numbers are up. 

At least 319 people have been slain in Chicago this year, about a 50% increase over this period last year. The number of shootings and the number of shooting victims in 2016 have increased at about the same rate.
