In Belgium people do have an expectation of privacy in public, what they did is straight up illegal under Belgian law. If they want to film or photograph a person (not as an accidental passerby, but as the subject as was the case here), then they need to get consent from that person. If they want to share that footage online, then they need consent for that as well.




The generally refers to the exceptions where no consent is needed. Had the ladies been committing a crime, then no consent was needed to start filming. Had they been filming some landmark and the ladies walked through the frame, again no consent needed from them. But generally speaking, consent is required before you may start filming a stranger.
