In the wake of the terror attacks in Paris, where a suicide squad targeted a major soccer match, police unions are asking the NFL to reconsider its policy of barring off-duty and retired police officers from carrying guns inside stadiums.

The Fraternal Order of Police Ohio sent a letter to the Cleveland Browns and Cincinnati Bengals organizations last week asking them to rescind the restrictions on carrying firearms inside their stadiums.

"We live in an increasingly dangerous world and we saw in Paris that the terrorists are targeting large groups of people," McDonald said.
