Lupe Valdez, the sheriff of Dallas County, Texas, spoke during the Democratic National Convention, giving a mostly apolitical speech that called for understanding between police and minorities.
She also led delegates in a moment of silence for law enforcement officers who were killed in the past several weeks. Three officers were killed in Louisiana and five were killed in Dallas.
Valdez, the only Hispanic sheriff in the United States, said that open dialogue between law enforcement and minorities is the only way to restore positive relationships.
