The police in Bangladesh presently spend a great deal of their time in writing diaries of cases and investigations by hand. The system has hardly changed since the colonial era. Records of criminals are similarly kept hardly befitting the need for speed when the soaring number of crimes and the voluminous investigation reports dictate much speedier handling. In some police stations of the country, files of years ago even turn unreadable from disuse and the careless or unprotected filing system. Computers can come to the rescue in such a situation. A single computer in a police station can make redundant thousands of files accumulated over the years and release space at the station and extra time for the policemen for their field work as they would not have to do so much tedious writing work.
Furthermore, computerisation can tremendously aid detection of criminals as their pictures can be preserved in computers and the same can be brought to the screen any time through the flick of a mouse.
