WASHINGTON, Sept 26, (APP/AFP) – Violent crime jumped nearly 15 percent in America’s biggest cities last year, the Federal Bureau of Investigation announced Monday, amid an increase in murders in large cities ravaged by gangs. In its annual “Crime in the United States” report, the FBI counted an estimated 1,248,185 violent crimes last year, a 4.1 percent increase from 2015. Murder and non-negligent manslaughter offenses jumped 8.6 percent — most of those crimes perpetrated with firearms — while aggravated assault increased 5.1 percent and 4.9 percent, respectively, and robbery inched up 1.2 percent. In the 30 biggest US cities, murder increased 14.8 percent. Chicago, home to less than one percent of the US population, accounted for more than 20 percent of the jump in murders nationwide, noted The Brennan Center for Justice. Yet crime is far from the peaks of the 1990s.
