The road is closed with a non regulatory sign, the vehicles and the the driver are allowed to access the road by law if they have a legitimate reason, the red sign has been deliberately placed in the area which should be open for access, I suspect by the man with the camera. The restriction can only be enforced if a police officer sees a vehicle passing the signage, then the officer would have to warrant that the driver of any of the vehicles didn’t have a legitimate reason for passing the barrier. That the law, remember the Highway Code is not the law, it’s a guide. Unfortunately the man with the camera is attempting to enforce a law which he cannot uphold.
You seem to go out of your way to antagonise people like you want a reaction, this may well one day backfire because some people aren’t phased by a camera, fair enough you do what you do but you seem to further aggravate people in the hope of a reaction then it’s “I’ll call the police” thus taking the police away from real policing for something you brought on your self,your not the police or a traffic warden leave enforcing to the real people cut out for it, also should be a law against filming people without consent if you ask me,
I have watched this several times now and cannot see that this man "attacks" anyone. He raises his voice but that's it. The South African guy completely overreacted imho.
