When Scott Daniel Warren was arrested last year after allegedly providing food, water, beds and clean clothes to undocumented immigrants near Arizona's Sonoran Desert, the question was whether he had broken the law or upheld it.
"No Más Muertes," an advocacy group that wants "no more deaths" of people crossing the desert regions linking Mexico and the southwestern United States, sees Warren - one of its most visible members - as an apostle of humanitarianism. His advocates say the geographer, who has taught courses at Arizona State University, was heeding both religious rules and international covenants that require sanctuary for the persecuted and the dispossessed.
