The DCRBX will also have a major role to play in closely supervising and monitoring the maintenance of crime records at the Police Stations. Another major advantage in having a well organized, DCRBX will be greater coordination between Police Stations within the district and inter-district coordination in crime investigations and other related activities of the Criminal Justice Administration.
