What happens when I have a passphrase that's a confession to a crime that I was forced to provide?

What if I forgot my passphrase due to the stress and trauma of being associated with a horrible event or merely at the stress of being detained? Am I to be detained indefinitely without due process and without being accused of a crime?

What if the passphrase was set by my wife and I, a personal and private communication that is not in direct association with the crime under investigation?

Would be nice if you could not turn my individual liberties into Swiss cheese. I can barely see the parchment.
