As the country reels from continued mass shootings and a Supreme Court decision that makes it easier to carry a concealed firearm, we revisit the story of one of the most prominent figures in the fight for gun reform. In 2011, then-Arizona Congresswoman Gabby Giffords survived an assassination attempt when she was shot in a parking lot. A new documentary tells her story, and charts her recovery and activism. Co-directors Betsy West and Julie Cohen joins us to discuss the film, "Gabby Giffords Won't Back Down," in theaters now.
