At CPH:DOX this year they showed the documentary "Phantom Parrot" about human rights activist Muhammad Rabbani that was prosecuted for refusing to give up his passwords at a border crossing into the UK.

The surveillance programme, codenamed Phantom Parrot, is designed to copy the personal data of individuals at airports and border crossings.

There's a trailer for it here: https://youtu.be/8QzZteMWbww
