I'am trying my best to give this reply.
As per my opinion, there must be a provision in the statute, facilitating the I.O to prepare a notes during the course of investigation. And at the same time, he is supposed to recoed the statements of the witnesses at the scene of offence and prepare a rough sketch of the offence as well.
But now a days this procedure is not followed by any of the I.O's throughout the country. Why is it So?
Moreover, the entire paper work related to the offence is prepared in the Station house itself. It is only because the police are'nt able to reach the scene of offence in time.
The notes of the I.O may not form the part of the record, but the contents of the notes will be depicted in the record to make believe the Court as recorded at the scene of offence.
Thank you for your patience..
