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 Newarkers to say they have had
enough.
Grassroots organizations, like Stop Shootin’, 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 50000 to promise to "stop shootin’,
start thinkin’, and keep livin’." 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.
Mr. Booker, as well
as church leaders and others, believes (or hopes) that after the murder the city
will no longer stand by in coldness. For generations, Newark has been paralyzed
by poverty— almost one in three people lives below the poverty line—and growing
indifference to crime.
Some are skeptical. Steve Malanga of the
conservative Manhattan Institute notes that Newark has deep social problems:
over 60% of children are in homes without fathers. The school system, taken over
by the state in 1995, is a mess. But there is also some cause for hope. Since Mr
Booker was elected, there has been a rise in investment and re-zoning for
development. Only around 7% of nearby Newark airport workers used to come from
Newark; now, a year later, the figure is 30%. Mr Booker has’ launched a New
York-style war on crime. So far this year, crime has fallen 11% and shootings
are down 30% (though the murder rate looks likely to match last year’s
high). |
The best title for the passage may be ______.
A:Stop Shootin’, Start Thinkin’, and Keep Livin’ B:Efforts to Fight against Gun Crimes C:A Mission to Revitalize the City D:Violent Murders in Newark
