Hearsay.
hearsay but certainly fits doesn’t it?
It would not be allowed to be entered as direct evidence at trial because of the hearsay rule, BUT it could be used to impeach the declarant should the declarant be called to testify and then say something different than what is on that tape.
Also, the hearsay rule does not apply in a grand jury. It's completely admissible there, and may be weighed as evidence by the jurors.
