Article 19:
Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.
Seeking and receiving information covers gathering facts, evidence, or observations from public events or spaces (e.g., documenting protests, government actions, police conduct, or everyday occurrences visible in public).
You might not like it, but its a key mechanism by which we, the people, keep despots and the police state in check.
