When a hearsay statement, as defined in this chapter, has been admitted in evidence, the credibility of the declarant may be attacked, and if attacked, may be supported by any evidence which would be admissible for those purposes if the declarant had testified as a witness. Evidence of a statement or conduct by a declarant-at any time-inconsistent with his hearsay statement, is not subject to any requirement of previous confrontation, so as to give the declarant an opportunity to deny or explain such statement or inconsistent conduct. If the party against whom a hearsay statement has been admitted calls the declarant as a witness, the party is entitled to examine him on the statement as if under cross-examination.
