The UK's laws to compel people to give up passwords seems to make it a de facto crime to forget one's password. Worse yet, it seems like it's illegal to possess random bytes on your devices. I wonder if the UK would change course if people started emailing random bytes to politicians and other supporters of this law, while giving tips to law enforcement that these individuals are coordinating criminal acts over encrypted communications.

But ... If you're going to compell someone to give up the contents of their mind under threat of being found guilty if their mind isn't working properly, you may as well just do away with trial.

IOW, if you're going to compell speech, just compell the suspect to confess; it's the same thing.
