Hillary Clinton said Monday she had met with the family of Philando Castile, the 32-year-old cafeteria worker who was shot and killed by a cop during a traffic stop in a St. Paul, Minnesota, suburb.
She described them as courageous, NBC News reported, and told the American Federation of Teachers convention in Minneapolis that the country had been "confronted with tragedy too many times recently."
"We cannot let this madness continue," she said. "This violence cannot stand."
She also praised the work of police officers in keeping communities safe, turning to the ambush killings of cops in Dallas, Texas and Baton Rouge, Louisiana.
