As fires rage across the West, we dig into the lives of hotshot firefighters. Fernanda Santos, Phoenix bureau chief for The New York Times, likens them to "migrant farm workers chasing harvest time from state to state." In her new book, "Fireline," Santos writes about the 19 hotshots who died in Arizona's Yarnell Hill Fire 3 years ago this week. Then, the connection between legal marijuana and homelessness. People are coming for pot, but not all of them find housing. Plus, students at the University of Colorado Anschutz Medical Campus are studying the role doctors played in the Holocaust.
