Travis is a teenager living in a small town in the Northeast. He enjoys hunting and shooting, and keeps a rifle at home. But with several younger siblings around the house, he wanted to make sure his gun was safe. So he ordered a trigger lock on Amazon, to prevent the gun from firing.
"The reviews were great, five-star reviews," says Travis, who asked that NPR use only his first name to avoid scrutiny and possible legal attention. "[They] said it worked great, locked perfectly, the combination system worked great."
