Authorities say at least 71 people were shot in Chicago over the weekend. Eleven of those people died. 

Chicago Police say over a 24 hour period, 34 people were shot and five died.

The youngest survivor is an 11-year-old shot in the leg.

Chicago Police says everyone has to be held accountable, not just law enforcement.

Some want the resignations of the city's police superintendent and Mayor Rahm Emanuel.

During a press conference on Monday, the mayor said, "What happened this weekend did not happen in every neighborhood in Chicago, but it is unacceptable to happen in any neighborhood of Chicago."

Chicago's mayor says one lesson from a wave of weekend violence is that people who live in neighborhoods where the shootings occurred have to be willing to name potential suspects.

Emanuel says residents must be willing to "speak up" and help identify suspects. 

Emanuel says the weekend shootings were concentrated in just a few neighborhoods on Chicago's West and South Sides, in areas where street gangs are entrenched.

On Sunday, police pointed out that – despite the weekend violence -- murders in the city are down 25% so far this year. Shootings are down 30%.
