On this week's Click, when the FBI came knocking on Ladar Levison's door they wanted the secret keys to the email service he ran. Why? Because Edward Snowden was using his email service - Lavabit - and they wanted acess to his communications. Rather than giving the keys up, he chose to shut the service down and this week has been in court - in a case which has profound importance to the internet as a whole - fighting the US government over whether their action was lawful. We've spent the week with Ladar Levison.
