By contrast, according to James Alan Fox, Northeastern University criminologist, between 1980 and 2010 there were, on average, 20 mass murders a year (defined by the FBI as four or more killings in the same incident) with an average annual death toll of about 100. That’s a mere 0.01% of the average homicide total.

If we want to save lives by preventing gun deaths, the larger problem of individual homicides, suicides and accidents is the place to begin, not events such as Sandy Hook.
