We’re learning of yet another mistake by D.C.’s 911 call center that caused a delayed emergency response. A man having a heart attack walking to get a prescription died despite three calls to 911 for help. We talk about the incident and the state of D.C.’s Office of Unified Communications which oversees the city’s 911 with the man who broke the story, longtime safety advocate Dave Statter. And we’ll bring you a new batch of ideas in this week’s DMV Dates segment.
