They have both been modified to stress the decision-making requirements essential for effecting identification. 2 All training programs for latent print examiners place great emphasis on practical experience during the phases of instruction regarding the evaluation and comparison of latent prints. This emphasis is well founded and has considerable merit, but it has been stressed so heavily that little written information exists regarding the methodologies and procedures for making a comparison of two prints.
It is quite obvious that if fingerprint forms are filed according to this system, the searcher chooses the bundle bearing the appropriate Henry fraction and merely searches this one bundle. There are further subclassifications, which mean that every bundle can be further divided for searching. Unfortunately, some fingerprint patterns merge their characteristics and have to be searched as alternatives, meaning that additional bundles have to be examined in order to positively conclude a search. It must also be remembered that missing or bandaged digits have to be further searched to cover all possibilities.
