A suspected shooter who opened fire inside an elementary school in Nashville, Tennessee was armed with a handgun and two assault-type rifles, firearms that have been used in some of the nation’s deadliest mass shootings over the last decade while dominating the American gun market.
About one in 20 US adults – roughly 16 million Americans – own at least one AR-15-style rifle, according to polling from Ipsos and The Washington Post, which traced the explosion of the popular firearm from its military use into one of the nation’s most popular and deadliest weapons. One of the firearms carried by the Nashville suspect was an AR-style rifle, according to police.
