The whole point of a justice system is that Occam and his Razor are a terrible way of determining guilt.

Yeah, I'd bet that most people claiming to have forgotten a key or password are lying. But so what? How do you differentiate those who're concealing vs. those that legitimately don't know the string of characters? If they float, they're a witch, if they sink, then I guess they're not? (That's what 18 months for contempt is akin to)

You differentiate them using circumstantial evidence. Was the encrypted disk found under a pile of dust in the attic? Then to forget the password is quite believable. Is there independent, convincing evidence that you regularly and recently used the password? Then you’re probably lying. Or maybe you’re just really unlucky. Wrongful convictions do happen.
