Myth of the Day

There should never be a second analysis conducted because of the potential for conflicting forensics reports.
Category: All DME Myths
If the first forensic analysis is properly conducted and reported, any subsequent analysis should not ever result in a report that truly contradicts the first report, as far as factual findings are concerned. Opinions, if any, may vary in different reports. It may be that a subsequent examination resulted in finding additional data not found during a prior examination because the information found during the earlier examination seemed to satisfy the requirements of the request at that time. Additionally, the prior examination may have been suspended or terminated prior to completion, pending further request.
