That's not it. Recording in public is legal there. These commies don't want to be recorded, move. Irony is China is full of surveillance. Just ask the Uighurs. I am glad this guy didn't cave. He is too kind. If it's me, I would tell them to fuck off and end the conversation there. I guarantee if you do this, like these commies did, in China as a foreigner, you will get arrested immediately.So to review...
A guy takes a video in a public place, probably without a permit.
Some passerbys ask him not to use their images in the video.
He starts ranting at them about their nationality, even though under the laws of his country, he should be getting signed releases.
A police officer stops by and tells him to stop acting like an ass.
