While I do agree that he is a "witness" I do not understand why anyone needs to "authenticate the Tape Recording".

He needs to authenticate that the tape is exactly as he made it, that it hasn't been doctored... In this day and age, it is very important.

Exactly. Unauthenticated evidence is not admissible in court, and cannot be used to convict. Period.

And that includes videotapes.

Or that there are no copies thus indicating that the only tape can be doctored. In this day and age, it is very important. Very important to think not just critically, but from all perspectives think critically.
