I agree with you. Filming evidence of a crime should always be legal. But I will say that posting negative videos of people to social media is considered libel in some countries. There’s a line where freedom of speech ends and harassment begins.

I would say secretly recording a politician as they admit to corruption and sending it to journalists and the police is ok, but filming a politician when you ask them loaded opinion questions and then posting it to social media to dunk on them is not.
