- Casey Anthony Trial - A Call For Validation Testing�-�While moderating CLE sessions at the Carmel Valley eDiscovery Retreat this week, I received multiple emails from clients and contemporaries drawing my attention to the breaking scandal around the erroneous web cache forensic reports in the Casey Anthony trial. As it happens, one of my sessions with Herb Roitblat and Jason Velasco was “Validation Testing – Defending Your eDiscovery Process”. I have not been able to get a more detailed analysis of the exact issue with the CacheBack software used by John Bradley (the designer) as yet. The primary problem was that his initial analysis showed that someone on the Anthony residence computer had run searches for “Chloroform” 84 times when it was later determined that this had happened only one time. This is a good example of how even the best intentioned and experienced user can come up with erroneous results in unusual or unanticipated circumstances.

Firefox Versions 1 & 2 used a rather unique and problematic database file coined “Mork” after the quirky TV alien ‘Morky & Mindy’ TV show.
