A recent surge in violent crime in many parts of the United States has raised concerns. In Chicago, 40 people were shot over the weekend, 11 of them fatally, according to local media. Los Angeles police say there have been significantly more homicidal deaths in the city this year than in previous years. New York state has declared a state of emergency over a surge in gun violence... There is growing concern about the growing problem of violent crime in the United States. "Crime is out of control and there is a war on the streets of America," says Jeanina Pirro, a former judge in New York state.
