HOUSTON — The City of Houston has released a video designed to teach people how to react during a workplace shooting by emphasizing a three-word mantra: run, hide, fight.

The video was funded with $200,000 in federal grants and released following last month's movie theater shooting in Colorado.

Houston Homeland Security official Richard Retz says the theater shooting convinced city officials to release the video early, though they still plan to make it part of a wider safety campaign.

In the video, ominous music plays before a narrator warns that life can occasionally feel "more like an action movie than reality." Then, a man opens fire in an office building.

The video has been viewed more than 220,000 on YouTube. Retz says hundreds of cities and agencies have asked to use it.
