As an 8-year-old, Luis Mora, like a lot of kids, walked home from school every day. He would take the same path home — across a covered bridge, down a flight of stairs and along the road until he got to his home in Quito, Ecuador.
One afternoon, as he crossed the footbridge, a teenager walked up to him, held a gun to the second grader’s chest and demanded his cell phone. (Mora’s parents, who worked long hours, had given their son a phone so they could easily stay in touch with him throughout the day.)
