Legality of Video taping for evidence examinations?

Question

I work for a Fire and Arson investigation company in Southern California. From time to time we hold examinations of our evidence with the opposing side of our client. The people that come to examine the evidence are engineers and lawyers mostly, again for the opposing side. I have had a few people that requested the audio to be turned off for the recording, or they wouldn't continue and they state it is against the law to have audio being recorded. Is this true? If so can someone give me a reference?

Thanks in advance.

Answer 1

It is only against the law to record a confidential communication without the consent of all the participants. So, if there is an objection AND the conversation is confidential, then recording it would be illegal. It would not be illegal if either it was not confidential, or everyone consented to the recording.
