Violent crime in the United States fell for the fifth consecutive year in 2011 with murder, rape and robbery all going down, although crime remains a serious problem in many urban areas, the FBI said on Monday.
James Alan Fox, a criminologist at Northeastern University, said crime has continued to decline from a peak in the 1990s but now is decreasing at a slower rate.
“I call it the limbo stick effect,” Fox said. ” You can only go so low. You’re never going to get down to zero crime.”
