The Grand Junction Police Department instructed an hour long course Monday morning at the City Council's workshop at City Hall.
The objective was to inform and prepare the members for an active threat of violence, such as a gunman, if that were to ever become a reality.
Included in the presentation were tips on how and when to issue a building lock down, as well as when to run from danger, hide from it, and even fight back.
The Council will go through a live demo of such an instance at some time in the near future.
Police representatives say it will be as realistic as they can make it, and is essential in order to develop appropriate responses.
