A careful glimpse of the lips instantly tells us the mood of the individual. The lips are the most expressive and the most mobile, or flexible facial feature, but in its normal relaxed state, it can be described quite accurately. Since the tendency is to watch the lips of another when he or she speaks, sight recognition of the lips should have a more lasting impression and the witness will be able to describe the lips better than any other facial feature. Thus the description of lips becomes an important aspect in facial recognition and identification.
The microstructure (grooves and wrinkles) contrary to the earlier findings, are not age-sable like finger prints, neither are they ‘environmental-stable’. Therefore there may be some working disadvantages when lip prints of criminals are compared after a long lapse of time with the crime prints made earlier.
Nevertheless, the macrostructure, namely, the size of the lips, the shape of the oral fissure, upper and lower vermillion borders and protrusion of lips are age stable and environmental stable. Therefore the classification system of macrostructure can be potentially used for the processes of personal appearance identification. If witnesses can describe correctly the above five parameters, then it will easy to searching for the suspects could be narrowed down to one in 8640.
The author has developed a universally applicable language to obviate the difficulty in using proper terminology by the witnesses and the inability of the investigating police to understand what the witnesses speak. The terminology developed by the author could easily be used by the witnesses and could easily be understood by the investigating police.
