Fourth of July weekend shootings in Chicago left nine people dead and at least 53 others injured.

“We need some help here, folks,” Police Superintendent Garry McCarthy said Sunday, CNN reported. “We have to fix this broken system. Criminals don't feel the repercussions of the justice system."

“We must stem the flow of guns into the city,” McCarthy said, noting that since last Friday morning, Chicago police recovered one illegal gun per hour across the city.

This year's statistics may sound staggering, CNN said, but compared with last year, the number of violent incidents is actually down. For the same period in 2014, there were 64 shootings, 69 nonfatal victims in those incidents and 15 slayings.
