A former D.C. police officer was sentenced to 15 years in prison Friday in connection with the 2009 attempted robbery of an alleged drug dealer, which resulted in the fatal shooting of one of the co-conspirators during the botched crime. D.C. Superior Court Judge Michael L. Rankin told Reginald Jones, 42, that he betrayed his uniform when he served as a lookout in his police cruiser so that five other men could commit a robbery.
