Recordings of Physical Objects: Laying Foundations and Meeting Objections, Section 6 (Unabridged‪)‬

In evidentiary terms, the next best thing to seeing the object or the scene itself, or hearing a witness who was at the scene is a recording of some kind that accurately reproduces the "real thing". The authenticity or trustworthiness of many of these exhibits must be established under Federal Rule 901(b)(9) or the state equivalent that applies to processes or systems. The output from equipment can be qualified by testimony that the process or system produces an accurate result. This book explains how to put in this foundation and to defend it against objections.
