The horror at Uvalde in Texas shows American exceptionalism at its worst. But part of the tragedy is that the event in itself is not exceptional. In the ten years since the massacre at Sandy Hook, there have been more than 900 other shootings in schools across the country. Why can’t America stop gun violence?  Former firearms executive turned safety campaigner Ryan Busse explores how American gun culture has changed. We go back to the last time a president was able to pass lasting federal gun control legislation. And The Economist’s Alexandra Suich Bass considers what policies could help make America safer.  John Prideaux presents with Charlotte Howard and Idrees Kahloon.   For full access to print, digital and audio editions as well as exclusive live events, subscribe to The Economist at economist.com/uspod   See acast.com/privacy for privacy and opt-out information.
