Cowboys pay tribute to Dallas police before start of camp (Yahoo Sports)

In one wave after another, Jason Witten, Tony Romo and Dez Bryant walked arm-in-arm onto the field for the start of the Cowboys' training camp with families of the Dallas police officers killed by a gunman this month. It was their way of paying tribute to the five fallen officers, and it left an impression on Dallas police Chief David Brown. Families of four of the five officers killed in an ambush in downtown Dallas during a Black Lives Matter rally were represented, and children were among those holding hands with Dallas players.
