A Building Collapses Just as a Fire Truck Drives By

This happened yesterday in Washington D.C.  A home security cam filmed a building across the street collapsing just seconds after two people had walked by . . . and just AS a fire truck came down the street. 

The truck stopped immediately to check things out.  One person was hospitalized with injuries that were not life-threatening.  The building was being renovated, which is why it wasn't stable.
