A spokesman for the Cheyenne Police Department says police and other local emergency responders regularly practice how they would respond to terrorist and mass-shooting attacks.

Officer Dan Long says the training is on-going and changes to deal with a wide variety of potential situations. Long points to a recent drill that featured a scenario in which an active shooter opened fire at the Cheyenne Airport.

Officers responding to that drill knew it wasn't real, but had no advance information about exactly what would happen. Long says it's important that police conduct such drills in conjunction with the Laramie County Sheriff's Department, Cheyenne Fire and Rescue and local ambulance services because all of those agencies could be called upon to work together in the event of a real terrorist attack and/or mass shooting.

He says besides allowing police to practice how to respond to such emergencies the drills also test the ability of the different agencies to communicate and coordinate their responses.
