As expert witnesses, we have grown familiar with video conference depositions. Platforms such as Zoom and Cisco’s WebEx make virtual participation simple and easy. Yet many client attorneys have expressed concern about remote depositions, noting that this method inhibits them from seeing the witness in 3D. You only see what the camera sees.
Deposition by video also makes it more difficult to interpret body language and other nonverbal cues. And even though the witness is sworn in, Primeau Forensics has run across instances where we were able to scientifically prove that the witness lied under oath when the attorney’s had a limited line of sight.
A webcam’s field of view varies depending on the model. Most commonly, a webcam viewing angle lies between 50 and 90 degrees. These cameras have virtually no depth of field and certainly do not have peripheral vision like a human.
In a video conference deposition, attorneys are unable to see what lies next to or behind the computer screen. Items normally prohibited in a court of law may be present without the deposing attorney’s knowledge.
A few years ago, I had a case where a client-attorney whispered to their client throughout a remote deposition. We forensically enhanced the telephonic recording and could clearly hear the attorney whispering answers to the witness.
