with reference to the solution given for the examination of a cartrige, what are some of its classification systems?
The Roscher System, the Juan Vucetich System and the Henry Classification System.
Fingerprint
Before computerization, manual filing systems were used in large fingerprint repositories. A fingerprint classification system groups fingerprints according to their characteristics and therefore helps in the matching of a fingerprint against a large database of fingerprints. A query fingerprint that needs to be matched can therefore be compared with a subset of fingerprints in an existing database. Early classification systems were based on the general ridge patterns, including the presence or absence of circular patterns, of several or all fingers. This allowed the filing and retrieval of paper records in large collections based on friction ridge patterns alone. The most popular systems used the pattern class of each finger to form a numeric key to assist lookup in a filing system. Fingerprint classification systems included the Roscher System, the Juan Vucetich System and the Henry Classification System. The Roscher System was developed in Germany and implemented in both Germany and
who published a study of tool marks on bullets UNANSWERABLE how is the firearm examined during a criminal investigation? It is examined for serial numbers and potentially fingerprints. and how are the cartridges examined to give evidence in an investigation? By Fingerprint recovery how is the striated databasing carried out? Information uploaded to these databases can be used to track gun crimes and to link crimes together. Maintainers of these databases recommend that every recovered firearm be test fired and the resulting known exemplar be uploaded into the database what is the name of that portal where such details are uploaded? National Integrated Ballistic Identification Network (NIBIN) & National Ballistics Intelligence Service (NABIS). who owns and manages the first portal? The ATF who owns and manages the second portal mentioned? The British Intelligence Service
