An internal review of a little-known NYPD unit, the Confidential Rental and Leasing Office (CRALO), found that top police officials were assigned to vehicles meant to be used during undercover investigations, according to Police Commissioner Jessica Tisch. The vehicles were also assigned to units not involved in "confidential investigations" and were often used to drive to and from work. Tisch testified at a City Council budget hearing that the vehicles were "out of all control" and that no one found to have been wrongly using a CRALO vehicle was disciplined due to the abuse being approved by the department. The department has implemented new rules to ensure that executives are assigned a single car and not multiple cars, and that these vehicles are only being used in investigative commands.
