The rate of violent crime in the U.S. increased last year for the first time since 1993, the Justice Department said Wednesday. The increase was attributed to a 22 percent jump in assaults. The statistics include 3.9 million simple assaults without a weapon and resulted in relatively minor injuries. The category serious violent crime, which includes rape, sexual assault, robbery, and aggravated assault, had a statistically insignificant increase to 1.8 million. In the more violent category, the number of white and Hispanic victims increased, and there were more young men victims—but not young women.
