The men and women of the Orlando Police Department are receiving a collective pat on the back this week from their counterparts in Aurora, Colorado, who are familiar with the horrors of mass shootings.

In a new video posted online, members of Aurora’s police praise Orlando’s officers in the wake of Sunday’s mass shooting that killed 49 people and injured 53 inside a nightclub, the deadliest mass shooting in United States history. Among those giving praise in the video are Lt. Stephen Redfearn, who was among the first to respond in 2012 during a mass shooting inside a movie theater that killed 12 people.

“We want you to know that whether you were one of the brave men and women who heroically rushed to the scene and saved countless lives or took fire while confronting the suspect, we stand with Orlando,” Redfearn says in the clip.

Police in Aurora decided to record the video message of support to assist the Orlando officers who’ll be dealing with the trauma of Sunday’s attack for years to come. Similar messages were created for Aurora’s police force soon after the 2012 shooting spree.

Patrol men and women as well as detectives, crime scene specialists and support staff appear in the video, which represents the entire 787-member department’s response.

Aurora’s Chief of Police, Nick Metz, says that upon learning of the violence inside Pulse, the members of his department “felt an enormous sense of sorrow for the Orlando community and a great sense of empathy and connection to the men and women of the Orlando Police Department.”

The Aurora officers collaborated on the video as a way of lending support to Orlando’s cops, Metz explains in the clip.

“It goes without saying that the Orlando Police Department stepped up,” Metz says. “You all did an incredible job in protecting and saving lives that horrific night and for that, we salute you and we are incredibly proud to call you our brothers and sisters in blue.”

Officer Tomas Campagna adds: “We know what you’re going through. And while at the moment it may seem hopeless, we know you’re going to get through this as a community and as a police department.”

Aurora Policewoman Natasha Cabouet tells the camera that “even though we are separated by thousands of miles, we wear the same badge, the same uniform and share the same grief and sorrow.”

Aurora Police Commander Mike Dailey says the Colorado officers “are here for you and we grieve with you.”

The gunman in last Sunday’s shooting, Omar Mateen, was killed during the attack.

Next month, Aurora will mark the fourth anniversary of the theater shooting perpetrated by James Holmes.

Last summer, jurors convicted Holmes following a lengthy trial during which police officers and others described the vicious attack.
