Rubber hose cryptography isn't a valid response to plausible deniability, because it applies equally to a volume that's encrypted normally (i.e. the cops just see junk data). At least you have a chance to throw them off with your fake unlock. Anyway, if it comes down to torture, you're screwed no matter what (unless you're trained to withstand torture); plausible deniability is more for "civilized" courts because they can't possibly prove that you're withholding anything. Personally, I think the 5th amendment in the USA should mean you can't be compelled to decrypt your data anyway, but that's not how the courts see it.

actually that is how the courts see it
