A group of Democratic lawmakers in Colorado are considering a new ban on assault-style weapons after 10 people died in a mass shooting at a grocery store in Boulder on Monday. Republicans in Colorado oppose the ban and are pushing for more money for mental health services. The accused Boulder gunman is scheduled to appear in court today for the first time. In a major legal decision, the U.S. Court of Appeals for the 9th Circuit has ruled that states may bar people from openly carrying guns in public. The ruling could impact right-to-carry laws across the West and Hawaii and Alaska. Meanwhile, nearly 20,000 people died in the United States from gun violence last year — more than any year in at least two decades — this according to the Gun Violence Archive. Gun sales also jumped by 64% in 2020, with some 23 million guns sold in the United States.
