Pending approval from the NFL, the Dallas Cowboys will wear these "Arm In Arm" stickers on the back of their helmets this year to honor the Dallas Police Department.

The Cowboys opened training camp on Saturday evening by walking out arm-in-arm with members of the Dallas PD and their families as a sign of solidarity after five officers were killed and nine others were injured when a gunman opened fire on them on July 7. Dallas Police Chief David Brown and Mayor Mike Rawlings both addressed the team before players took the field for practice.
