Coloradans are hungry for solutions to gun violence. One idea comes from a new type of gun maker. A Colorado company is starting to sell so-called "smart guns," that use fingerprint and other biometric technology so that only authorized people can fire them. The guns are designed to prevent accidental shootings and suicides. Colorado Matters talks to Biofire founder Kai Kloepfer, who has been working on this idea since he was in high school in Boulder.
We first interviewed Kloepfer when he was 17 years old.
