Efforts to create restrictions on assault weapons at the federal government level intensified in 1989 after 34 children and a teacher were shot and five children killed in Stockton, Calif. with a semi-automatic AK-47 rifle.[4][5][6] The Luby's shooting in October 1991, which left 23 people dead and 27 wounded, was another factor.[7] The July 1993 101 California Street shooting also contributed to passage of the ban. The shooter killed eight people and wounded six. Two of the three firearms he used were TEC-9 semi-automatic handguns with Hellfire triggers.[8] The ban tried to address public concerns about mass shootings by restricting firearms that met the criteria for what it defined as a "semiautomatic assault weapon", as well as magazines that met the criteria for what it defined as a "large capacity ammunition feeding device".[9]:1–2
