Chief Cathy Lanier’s on the war path. In addition to threatening to fire several police officers involved in a recent incident in Columbia Heights, Lanier has handed Commander Hilton Burton — who sharply criticized Lanier during a Council hearing on the Charlie Sheen police escort fiasco — a demotion.

Yesterday, the District’s Office of the Inspector General has wrapped up its report on the whole Charlie Sheen escort brouhaha, concluding that the police officers involved in the escort didn’t do anything wrong.

Well, now this is just getting plain embarrassing for the Metropolitan Police Department. Despite the fact that the department’s chief, Cathy Lanier, said on Friday that she was “100 percent confident the proper procedure was not followed for a reimbursable detail,” the Examiner’s Freeman Klopott reports that the New York Rangers received similar treatment on Saturday as they traveled to the Verizon Center for a playoff game against the Capitals.
