Dallas Police Org. Upset at NFL Over Rejected Decals

A Dallas police organization says the NFL should reconsider rejecting the Cowboys' request to honor fallen cops with a helmet decal this season ... telling TMZ Sports "We are extremely upset by their decision."

We spoke to Sergeant Demetrick Pennie, president of the Dallas Fallen Officer Foundation, who tells us the league should use its platform to support their cause.

"The NFL had an opportunity to be leaders and advocates for change in law enforcement," Pennie says.

"These teams and players have a spotlight on them and could have helped bring awareness. If a uniform policy is keeping them from this, then why don’t they have every team wear the decals?"

Pennie says he appreciates the Cowboys' attempt, saying "they understand the sacrifices these officers made and we're happy they wanted to honor these heroes.”
