Relations between Fire and Emergency Medical Services department brass and its rank-and-file are “deteriorating,” Peter Hermann reports in today’s Post, and that is putting it kindly. At the direction of Deputy Mayor for Public Safety and Justice Paul Quander, police are looking into Tuesday’s twin ambulance fires to ensure, in Quander’s words, “nothing untoward is occurring.” Under questioning, he did not rule out employee sabotage. The firefighters’ union, meanwhile, bristled predictably at the suggestion something “untoward” might be going on. Enter D.C. Council Chairman Phil Mendelson, who told Hermann Wednesday the department “is becoming an embarrassment to the city” and said matters are in a “downward spiral.” With Quander’s involvement, Mendelson said, “the citizens are safe.” Asked whether residents are safe with Fire Chief Kenneth B. Ellerbe, Mendelson responded, “I said what I said.” More from WAMU-FMWJLA-TVWUSA-TVLoose LipsWNEW-FM and DCist.
