"Every time there's a mass shooting," says Reason's Jacob Sullum, "people who had already been in favor of gun control talk about how we need more gun control. . . they don't feel a need to really explain how [their particular policy] would have prevented this particular attack."

Nick Gillespie speaks with Sullum about the Las Vegas mass shooting, the country's narrative in the wake of tragedies, and why it's so difficult to have a fact-based discussion about guns, violence, and policy.
