Klarevas, who defines a gun massacre to be six or more deaths, says his own research for the book “Rampage Nation,” however, backs up Clinton’s statement.
Compared with the 10-year period before the ban, the number of gun massacres during the ban period fell by 37 percent, and the number of people dying from mass shootings fell by 43 percent.
But after the ban lapsed in 2004, the numbers in the next 10-year period shot up again — a 183 percent increase in mass shootings and a 239 percent increase in deaths.
