In 2021, a Ruger AR-556 was used in a mass shooting at a King Soopers grocery store in Boulder, Colorado. Families of five of the victims have sued Sturm, Ruger & Co. for "marketing its AR-556 pistol, which resembles a rifle, in a 'reckless' and 'immoral' way that promoted its killing capability and glorified lone gunmen." A 2005 law passed by primarily Republicans in Congress limits the legal liability of gun manufacturers. However, they can still be sued for their marketing practices.The Colorado Sun, "More relatives of Boulder King Soopers shooting victims sue gun manufacturer Sturm Ruger", https://coloradosun.com/2023/03/27/victims-of-colorado-shooting-sue-sturm-ruger/?mc_cid=1986e499ed&mc_eid=41211bda96
