The Dallas Cowboys began their first practice of training camp by paying tribute to the Dallas Police Department and family members of the fallen officers killed in the recent shootings downtown.
Dallas Police Chief David Brown, Mayor Mike Rawlings and the family members linked arms with Cowboys players and walked out onto the field, forming a circle.
