The lingering inquiry that Councilman Bernard Parks' office blames on Wave columnist Betty Pleasant has been dropped and will not result in criminal charges, according to David Demerjian, who heads the District Attorney's public integrity division. "He's lived in the district since 2002, when he took out papers to run for the council, and has not moved from the district since then," Bernard Parks Jr., the councilman's son and chief of staff, said today.
