(b)If a competent photographer cannot be arranged for locally, a photographer will be deputed from the Criminal Investigation Department on receipt of a requisition by wire. To save time, such requisitions may be sent from police-station officers direct, but a wise discretion shall be exercised and they shall be sent only when the corpse is identifiable and there is reason to believe that the photographer will arrive before the corpse is unrecognizable owing to.decomposition.
