The Chicago Tribune reports that 14 people were shot and 6 killed within a span of 15 hours this week, urging Mayor Rahm Emanuel to declare once again that “enough is enough” and demand that the city’s criminal justice system and gun laws “reflect the values of the people of the city of Chicago.”

We’re not sure what Steve Krakauer meant by appending “These lives matter” to his tweet but it certainly seems like an unnecessary bit of editorializing.

The most high-profile of the shootings was an apparent drive-by that killed a pregnant woman and a grandmother and injured an 11-month-old.

In the Back of the Yards shooting, family members were getting out of their car in the 5300 block of South Aberdeen Street around 7:15 p.m. when another car drove up and shots were fired, according to Deputy Chief of Detectives Eugene Roy.

Patricia Chew, pregnant with her third child, was shot in the right side, and her 11-month-old son, Princeton, was shot in the left side. The boy’s grandmother, Lolita Wells, was shot in the leg, according to relatives and police.

Unfortunately, the “14 shot” figure includes only that particularly violent 15-hour span.
