In the United States, the gun debate has been raging for decades. Gun rights advocates think there are enough -- or maybe too many -- laws restricting their second amendment right to bear arms. Those wanting more gun control believe that to protect people’s safety, we need the government to regulate who can have a gun. But what happens when technology is one step ahead of the laws? That’s the case with 3-D printed guns. It’s always been legal for adults to make their own guns at home, but traditionally, that required specialized tools and a lot of skill. 3-D printing, however, is changing that, making it significantly easier to make a gun from scratch. This has sparked both interest from gun enthusiasts and concerns about public safety. Host Shirin Ghaffary explores how 3-D printed guns are affecting the gun debate in the United States.
