the prosecutors must prove to a very high standard that you do actually know the key, and haven't really forgotten. For instance if you typed in the password the day before you were arrested, that's probably a good sign you know it.

I've had a few occasions where, after 2+ months of using a password at least 5 times a day, I roll into work and just can't login. I still know the password I used when I was 9 and dialing into AOL, but my work password rotation policy is so strict I just don't have long term storage for them anymore. I mostly rely on muscle memory the current password too.

So, all that was to say I don't think that standard is "very high" at all.

Not to mention how badly stress can screw with memory.

If you're used to entering your password in a specific relaxed situation and now you're filled with dread every time you think about it, damn right you might not be able to remember it. That's just basic neurology.

Which is why we need to wash all that stress out of your head by holding it under water for arbitrary amounts of time...

Yes! There are times when my motor memory recalls the password just fine. But, if I specifically think about the password and can't consciously recall it, at that point the motor memory seems to reset and fails too.
