When mass shootings take place, libertarians at Reason and elsewhere usually respond by pointing out that gun violence is declining even as the number of weapons in circulation is climbing; that mass shootings are not increasing in number; and that most proposed solutions either won't work and raise serious civil-liberties concerns. These points are all true and important. But are they the limit of all meaningful response? In today's Reason Podcast, Katherine Mangu-Ward, Peter Suderman, Robby Soave, and Nick Gillespie discuss what if any policies might mitigate the frequency and casualties of mass shootings. They also talk about how Rush Limbaugh, of all people, has advanced the most progressive immigration policy heard in several months, whether the investigation of Russian influence into the 2016 election will undermine belief in American politics, and the deeper meanings of Black Panther, the latest Marvel superhero movie that is setting box-office records.
