FedEx is standing behind a driver who stopped protesters from burning American flags in Iowa.

According to the Iowa City Press-Citizen, a group of demonstrators set fire to the flags Thursday at a pedestrian mall in Iowa City during what organizers called a protest against racial injustice, social injustice and U.S. imperialism. That's when FedEx driver Matt Uhrin rushed onto the scene with a fire extinguisher to put out the flames.

Police said two people were arrested at the rally and charged with violating the city's public burn ordinance, the Press-Citizen reported. The group claimed the protest was within their First Amendment rights, but officials said the protesters did not have the proper permits to start a fire.
