As for the prohibition against the prosecution’s private recording of the proceedings, courts usually disallows such recordings because they create an unnecessary distraction and if allowed, could prompt every lawyer, party, witness, or reporter having some interest in the proceeding to insist on being given the same privilege. Since the prosecution makes no claim that the official recording of the proceedings by the court’s stenographer has been insufficient, the Court finds no grave abuse of discretion in Judge Yadao’s policy against such extraneous recordings.
