Yeah, he has some guests that get pretty far out there at times. :) But he's been very serious on this issue, with a factual approach. I don't think I'll suggest using anything as speculative as reversed speech or psychic stuff.
I just send links to information that he or his staff could possibly confirm for themselves. That's my standard SOP with media who I know to already be familiar with an issue.
(But if there's anything to reversed speech, it might be very interesting to hear MS.)
