People in Colorado will soon have to pass a background check and complete a state-sanctioned safety course to buy most semiautomatic guns with detachable magazines under a bill signed into law by Democratic Gov. Jared Polis on Thursday.
Colorado, which has seen some of the country’s worst mass shootings — including the 2022 killings at the LGBTQ+ nightspot Club Q in Colorado Springs and the 1999 Columbine High School massacre — joins nearly a dozen other states in requiring some level of safety training or an exam to purchase a firearm.
