As the nation continues to reel after the massacre at Uvalde, we are joined by Professor Adam Winkler, the leading expert on gun policy and gun laws, who takes us through the range of the possible when it comes to gun legislation.  What might Congress do, what are the limitations, political and constitutional, and what is the significance of the upcoming Supreme Court decision in Bruen?  Professor Winkler also offers a primer of sorts on the terminology and landscape of this highly contentious, highly fraught area of law and policy and a crucial time.
