So says all the media everywhere. But that is complete BS. In April 1993, at Waco Texas, eighty-two people died, some shot by the ATF, others burned in the fire they started. Going further back, in December 1890, at Wounded Knee, South Dakota, three hundred unarmed Indians, the majority women and children, were killed by the 7th Cavalry.
So Orlando is only the biggest ever mass killing if you don't count the government.
