The assassination of five Dallas cops last July left Dallas, TX, and the whole nation in shock. NFL team Dallas Cowboys wanted to honor the fallen cops with an Arm-In-Arm decal on their helmets, but the league said the team must remove the decals once preseason starts.

Owner Jerry Jones and Jason Witten, the team’s tight end who created the decal, expressed disappointment with the decision, but believe “the stickers already served its purpose.”

The police department, Police chief David Brown, Mayor Mike Rawlings, and members of the killed officers marched arm in arm with the Cowboys team onto the field to their first practice on July 30.

The police department thanked the Cowboys for their support:

The Dallas Police Department sent out a news release reacting to the news Thursday afternoon. In it, the department said the sentiment mattered more than the results.

“We appreciate the support of the Cowboys organization and its players,” the statement said. “Their concern for the families of our fallen officers, the Dallas Police Department, and the City of Dallas is what matters most, and we know that support will continue for the immediate and long term future.”

But members of the Dallas Fallen Officer Foundation were not pleased:

“The NFL had an opportunity to be leaders and advocates for change in law enforcement,” Sgt. Demetrick Pennie, president of the foundation, said.

“These are our friends and our loved ones … it hurts to not have the NFL fully support us,” he added.
