Has there been something more recent than this case? http://www.thenewspaper.com/rlc/docs/2011/ca-macias.pdf http://www.thenewspaper.com/rlc/docs/2011/ca-macias.pdf "Here, Officer Berg did not qualify as the appropriate witness and did not have the necessary knowledge of the underlying workings, maintenance, or recordkeeping of the Redflex Traffic System. The foundation for the introduction of photographical evidence and the underlying workings of the Redflex Traffic System was outside the personal knowledge of Officer Berg. In absence of a proper foundation, the photographic evidence was held inadmissable." The officer cannot be the accuser and introduce the evidence if he has no expertise in how the evidence was obtained.
