The fingerprint classification system used in most English speaking countries was devised by: In the Primary Classification scheme, the left index finger has a potential value of: A final conclusion made using the ACE-V process is either the individualization or elimination of a print (T/F). Fingerprint examiners use the ACE-V (analysis, comparison, evaluation and verification) method to reach a determination on each print. If your current cartridge is one of those then good to go (but will need to think about a the frequency of replacement). Some surfaces like highly polished firearms, well-handled plastic bags and bottles are much more susceptible to over-fuming than other types of evidence and must be watched carefully throughout the process. f.
