Even with four men charged in connection to a mass shooting in Chicago that injured 13 people, including a 3-year-old boy, some officials say the city needs outside help to police areas prone to gang violence, the Christian Science Monitor reports. Yesterday, police charged the four men with three counts of attempted murder and three counts of aggravated battery with a firearm. Police say two of them opened fire on the crowd at a basketball court in retaliation for a gun wound one got earlier in the day from a rival gang. The men did not target any particular person, police say, but shot into the crowd to make a statement because the park was located in rival gang territory. Chicago Alderman Willie Cochran welcomed an offer from Illinois Gov. Pat Quinn to send the Illinois State Police into troubled city areas. Chicago police superintendent Garry McCarthy said: “No way. No how. It's not an issue of resources. Let's stop the hysteria.” The labor union representing Chicago police officers says a major factor contributing to the violence is a manpower shortage, due to budget cuts enacted by Mayor Emanuel shortly after he took office.
