The National Football League—sometimes mocked as the “National Felon League” due a rash of violent crimes committed by current and former players in recent years—has denied a request by the Dallas Cowboys to wear a small sticker on the back of their helmets which would honor the five Dallas Police officers murdered by a domestic terrorist affiliated with the Black Lives Matter movement.

The NFL denied the Dallas Cowboys’ request to wear a decal on their helmets during the season that would have paid tribute to the five police officers killed last month in an ambush.

The team had been wearing a decal with the words “Arm in Arm” since the first day of training camp this summer. Dallas police Chief David Brown and Mayor Mike Rawlings paid the team a visit on that day, according to Fox 4 News.

The NFL’s strict rules on uniforms forced the league to deny the Cowboys’ request to wear the decal for the upcoming season.

Dallas police said it appreciated the Cowboys’ support.

“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,” the department said in a statement.

The simple “Arm in Arm” sticker is unobtrusive, but is apparently too much for NFL leadership, which has taken an ever-more politicized turn in recent years towards celebrating criminality over civility and decency.

The league did not punish St. Louis Rams players in 2014 who engaged in the “Hands Up Don’t Shoot” fiction embraced by Black Lives Matter after strongarm robbery suspect Michael Brown was shot charging a Ferguson police officer he’s previously tried to disarm.

They also allowed Beyonce to perform a very politicized Black Panthers-themed Super Bowl halftime show.

This is the same league which denied Daniel Defense the opportunity to buy an Super Bowl ad promoting the lawful self-defense of his family.

I applaud the Dallas Cowboys for trying to do the right thing, but the National Felon League to which they belong can rot.
