4 mass killings in 4 days show how random murder can be
USA Today - 10/31/2013
These numbers are part of the reason Jack Levin, a sociology and criminology professor at Boston’s Northeastern University, isn’t surprised that four mass killings happened in such a short time.
“Murders don’t distribute themselves evenly over a 12-month period,” Levin said. “Just because we see four occurring in proximity to each other doesn’t mean we are suffering through an epidemic of mass murders but that’s what people will think.”
