I have a box.
I put your best friend in the box and a red light comes on.
I say this means your best friend is guilty.
Your friend is put to death.
You have my word that the box and light does what I say it does.
When I put myself in the box, the red light never comes on.
Hmm, Joe Stalin had one of those. He even made a point of getting signed
confessions.
Another problem: someone commits a heinous crime, then doses eirself with
(say) a Rohypnol-Scopolamine cocktail that scrambles long term memory
fixation. Chemically-induced amnesia. What does a brain scan reveal?
"Quis custodiet ipsos custodies?" ...not to mention "Truth? What is truth?"
