Whether the Clinton-era ban on assault weapons, pushed through the Senate by Biden, was effective has long been a subject of interest for politicians and researchers — and The Fact Checker. Every few years, usually after a mass shooting, we find ourselves digging into the research to see whether there is fresh evidence to bolster the claims of Democrats that the ban was effective.

Over time, as more research has been published, the Pinocchio count has decreased. It also makes a difference how a politician frames the issue. Biden did not claim a “big drop” in deaths, as former president Bill Clinton did in 2019; Biden more modestly said the law resulted in fewer mass killings.
