Did anyone else hear him apart from Santa?

Because I keep hearing of these cases where person X has been locked up as a "terrorist" because person Y claims that person X made a "threat", but person X claims they didn't make the threat and there are no other witnesses.

If person Y is a police officer then person X tends to be out of luck as its impossible to disprove the accusation.

If someone told me in private they had a bomb I'd tell them to go and tell security. I wouldn't repeat the claim to anyone else because I wouldn't want to share responsibility for yet another unnecessary evacuation or for getting someone else (or myself) into trouble because of a misunderstanding. If anyone blamed me afterwards for not passing on the message I'd claim I misheard it: I thought they said they'd found someone's wallet, or something.
