What is The Scientific Method, and How is The Theory Applied to Fingerprint Analysis?

What is the scientific method ,and how is the theory applied to fingerprint analysis? The complete friction ridge identification process involves using the "identification philosophy and scientific methodology" in determining whether or not an "unknown friction ridge impression"(herein, called latent) came from the same source as a "known inked print (herein called print)to the exclusion of all others. (1) David Ashbaugh refers to this identification process as, "a guide of how friction ridge quantative-qualititive …

…methodology of framework. The "Five Step Formula"and "A.C.E."are two establishes identification processes that contain steps Latent Print Examiners can follow in making friction ridge identifications. Training,knowledge,experience and personal likings will determine which identification process an individual Latent Print Examiner finds most useful.
