This is the effect of having an authoritarian in charge. The propaganda that gets produced is done to convey a sense of power of the person/party, its popularity, and the scale of the internal and external “enemy threat.”
I think a lot of people have their fingers crossed on this one.
I believe that’s not the law though. The law outlines the conditions under which a person has an “expectation of privacy.” If you’re inside your house, you have an expectation of privacy and so should not be filmed. If you’re on the sidewalk in public, you have no expectation of privacy. If you’re in a private establishment (restaurant or store for instance), the owner or their representatives can ask you not to record and you have to comply.
All of street photography depends on this kind of legal framework.
