In US murder of a lady was traced from a recording.The killer was a stranger, and the lady was walking along the footpath just after alighting from a train. Just bcos of web footage this murderer was easily caught. Otherwise it would ve been very difficlt since the murderer had no link with the victim and the murder was done just to steal money. Since the recording can be made it can be reviewed any time. Suggestion was given bcos web cameras can greatly assist in keeping vigilance on the people
