Sure there is. All you have to do is use stegnography to encode your message into a photo, then use that photo in what looks like a spam email message, then pretend your computer is taken over by a botnet and send the spam to a few thousand email addresses (including the one you actually want to send to). Absolutely no useful metadata there.
Do you know what metadata is? It's the information like who it originated from and the destination address. That will still be

In America, there would be a strong argument that this is in contravention of the Fifth Amendment of the consitution (as it would be self-incrimination). Not sure how that's played out though.
But yes, in the UK, there is a specific criminal offense of "Not disclosing your encryption key" which carries a 2 year sentence... and you can of course, be asked to disclose your key again once you've served it...
I think that you would have a good chance of arguing that being asked again after serving a sentence would be attempting to try the same offence again, for which a sentence had already been server. Of course you never know which way courts will go though.
Its still in America so its subject to NSL, patriot act and all those other "freedom" laws they have. American crypto just cant be trusted, fundamentally flawed by law.
Is that right? I assumed that US law was like UK law - there is no law against using strong encryption but you can be compelled to give the encryption keys to the security services.
So, we're supposed to get excited because it has water? It has virtually no atmosphere. And from Wikipedia, the temperature never gets above 152K (that's -186F). Which of those two factors is going to allow for the evolution of any life form?
That's the surface temperature, liquid water oceans must be a lot hotter. Wikipedia estimates the core temperature as 1500–1700 K so there is certainly heat coming up.
Yet another pointless waste of money by the BBC.
Well - informing and educating is in it's charter and if done successfully it is a bit difficult to argue that it is more of a waste of money than many of their programs.
