Moses, (retired San Francisco PD) Edward R German, (US Army Criminal Investigation laboratory), and Kenneth 0. Smith, (US Postal Inspection Service), Carey L. Chapman, US Secret Service; and Stephen Meagher (FBI). Others from the original case in 1991 were involved also in the preparation. With these people, the government began preparation for the Daubert Hearing by developing a strategy for each Daubert element and identifying key witnesses for each subject matter.They began by conducting a survey of all 50 states, Canada and Great Britain to prove General Acceptance. What they did was conducted a statistical study with 50,000 prove fingerprints to provide quantitative assessment. With this effort they wanted to bring the worldwide use of fingerprint into the hearing. Also, to bring individuals outside the FBI into the hearing with their knowledge and expertise in the field of fingerprint. Numerous strategy sessions were held with selected groups of individuals. One of the most intense studies was the 50K statistical study. Lockheed Martin Corporation, under the direction of the FBI, conducted a 50K vs.50K fingerprint comparison study. First 50,000 left sloped loop as determined by the automatic classifier including references with white males only. Using the International Automated Fingerprint System5~ the FBI fingerprint system machine, they used matcher algorithms to run each fingerprint against the 50K file. By using the level two details only, which is ending ridges and bifurcations. The first was comparing fully recorded fingerprint, which is the same as known print. With this 2.Sbillion comparison was done as a result.The second study 21.7% of fully recorded fingerprint of simulated latent print gave a result of 2.5 billion comparisons. The conclusions of these were the first test the probability of a non-mate rolled fingerprint...
