Chicago 15 year old shot while walking on a sidewalk

What's the problem with just walking on a city street? This blog has reported on many of these kinds of shootings of late. This one is a 15 year old Chicago boy who was shot in the ankle by someone driving by:

A 15-year-old boy suffered a gunshot wound to the ankle and was taken in good condition to University of Chicago Comer Children’s Hospital while a 22-year-old was shot in the side was taken to Advocate Christ Medical Center in Oak Lawn, said Langford.

The two were walking in the area when a man or boy came up and shot at them several times, said Chicago Police News Affairs Officer Darryl Baety. The man was in serious condition at Christ Medical Center, police said.

Earlier this afternoon, a 21-year-old man was shot in the back about 12:40 p.m. in the 6600 block of South Artesian Avenue and was being treated in serious condition at Holy Cross Hospital, Baety said.
