The NRA wants to protect AR style semi-automatic rifles (referred to as assault rifles) from being banned. Therefore, they are quick to point out that most mass shootings in America have been carried out with handguns. Technically they are correct (if you go back far enough and ignore recent history). But, like most propaganda , the so called “truth” is often used to cover up the real truth. Next time one of your NRA friends claims you don't know the facts about guns, actually let them know the real facts.
Fact: Of the 10 deadliest mass shootings in US history, 5 involved an AR style semi-automatic rifle, 1 involved an Uzi, 1 involved a bolt action rifle, and only 3 involved handguns.
Fact: 50% of the 10 deadliest mass shootings in American history were committed with an AR. Handguns were used in only 30%.
Fact: Of the 10 deadliest mass shootings, 177 people were killed by an AR style weapon, 21 were killed involving an Uzi, 18 were killed by a bolt action rifle, and 51 were killed by handguns.
Fact: AR style weapons killed more than 3 times the number of people killed by handguns in the 10 most deadliest mass shootings in US history.
Fact: 6 of the 10 deadliest mass shootings occurred just within the last 10 years. 5 of them were committed with an AR style semi-automatic. Only 1 of them was committed with a handgun.
Let those roll around in their heads for awhile.
