　　The lives of very few Newark residents are untouched by violence: New Jersey’s biggest city has seen it all. Yet the murder of three young people, who were forced to kneel before being shot in the back of the head in a school playground on August 4th, has shaken the city. A fourth, who survived, was stabbed and shot in the face. The four victims were by all accounts good kids, all enrolled in college, all with a future. But the cruel murder, it seems, has at last forced Network to say they have had enough。

　　Grassroots organizations, like Stop shooting have been flooded with offers of help and support since the killings. Yusef Ismail, its co-founder, says the group has been going door-to-door asking people to sign a pledge of non-violence. They hope to get 50,000 to promise to “stop shooting, start thinking and keep living” The Newark Community Foundation, which was launched last month, announced on August 14th that it will help pay for Community Eye, a surveillance(监视) system tailored towards gun crime。

　　Cory Booker who became mayor 13 months ago with a mission to revitalize the city , believes the surveillance program will be the largest camera and audio network in any American city. More than 30 cameras were installed earlier this summer and a further 50 will be installed soon in a seven-square mile area where 80% of the city’s recent shootings have occurred. And more cameras are planned。

　　When a gunshot is detected, the surveillance camera zooms in on that spot. Similar technology in Chicago has increased arrests and decreased shootings. Mr. Booker plans to announce a comprehensive gun strategy later this week。
