Questions arise after DC, Arlington Boil Water Advisory

The last citywide Boil Water Advisory was 28 years ago and occurred over the Fourth of July holiday. That one lasted a week. This one was just about 12 hours, and we're told it was more of a precaution than an actual emergency. FOX 5's Bob Barnard has the latest details on the advisory issued to all of D.C. and Arlington County residents Wednesday night.
