Or that they play by the rules, or any rules that matter, to begin with. 
And that the user will be capable of lying through the teeth. Whereas 
the reality is that even in democracies a lot of law enforcement/border 
control officers will try to intimidate anyone they suspect of being a 
"bad person" (for whatever value of "bad person"). Try being olive 
skinned, having a few too many Middle Eastern passport stamps while 
having an Arabic name and getting through US border control with a 
truecrypt volume.

Other part of reality is that most normal people are incapable of lying 
all that convincingly under duress to an adversary that isn't willing to 
let them get away with it. Even your average politician, who is more or 
less vetted for being capable of bending the truth since not 
overpromising won't get you elected, typically cannot do it very well.

So yes, most of the "plausible deniability" schemes are just a load of 
bollocks. I am looking at you, OTR, you hateful, user-unfriendly pile of 
bovine excrement.
