While handguns are the most commonly used weapon type in mass shootings, assault rifles gained attention in public discussion over the suitability or necessity of semi-automatic rifles for the purpose of self-defense. Semi-automatic rifles such as the AR-15 have been used in a number of mass-shootings including the Waffle House shooting in Nashville, Tennessee, the Marjory Stoneman Douglas High School shooting in Parkland, Florida, and the El Paso, Texas Walmart mass shooting.
