“Did you further know that none of the killers involved in those massacres used assault rifles? Harris and Klebold destroyed 13 lives (not including their own) using two 9mm handguns and two 12-gauge shotguns. Seung-Hui Cho callously murdered 32 people using only a .22 caliber Walther P22 and a 9mm Glock 19.”
