A spate of high-profile mass shootings in the U.S. has sparked calls for Congress to look at imposing a ban on so-called assault weapons – covering the types of guns used in both the recent Buffalo grocery attack and that on an elementary school in Uvalde, Texas.
Such a prohibition has been in place before. As President Joe Biden noted in his June 2, 2022, speech addressing gun violence, almost three decades ago bipartisan support in Congress helped push through a federal assault weapons ban in 1994, as part of the Violent Crime Control and Law Enforcement Act.
That ban was limited – it covered only certain categories of semi-automatic weapons such as AR-15s and applied to a ban on sales only after the act was signed into law, allowing people to keep hold of weapons purchased before that date. And it also had in it a so-called “sunset provision” that allowed the ban to expire in 2004.
