tl;dr: Danish privacy activist and ex-cop Lars Andersen was arrested by masked police who broke down his door after he obliquely published PM Mette Frederiksen's social security and phone numbers, alongside criticism of her encryption-ban and mass-surveillance proposals. According to Andersen, officers immediately cut power to his router and seized his Nest cameras (which had local storage) to prevent the arrest from being recorded, and refused to state the charges against him.
