OK, I watched a repeat of the whole (well, I caught it from about five minutes in) documentary last night.
Of course we’re only seeing the side as edited by the BBC, but still, it looks as though this guy wanted to do a probing documentary on scientology and they (mostly by the action or direction of the sunglasses guy) harassed, threatened and obstructed him.
Couple of things:
-In the documentary, when the reporter is pursuing the sunglasses guy through the fairground, he doesn’t say the thing about freedom of speech in Britain - he attempts to continue his side of the discussion, saying something completely different - one of these pieces of footage - either the online clip or the broadcast documentary - must have been dubbed over with dialogue from another segment.
In the clip where he’s screaming/shouting, he intersperses it with a completely calm and composed question to the effect “Are you actually listening to me now”. It was very clear on the broadcast version that he shouted like this simply because the sunglasses guy kept interrupting him or cutting him off.
The sunglasses guy came across as really pissed off and beligerent - for example, the journalist was interviewing some other guy out in the street and the sunglasses guy rolled up with a dossier detailing some supposedly embarrassing personal details about the interviewee - he just butted in and completely hijacked the interview, making threats and being generally intimidating, and just talking loudly over the top of everyone else.
In the segment where they were interviewing some celeb scientologists, again, the sunglasses guy kept interrupting and talking over the top of the journalist, and wouldn’t let him address the camera - in frustration, the journalist and camera crew went to the rest room to try to take a few minutes calm to compose themselves, but were interrupted by the sunglasses guy banging on the door and calling through to them.
He also had the crew tailed everywhere on foot and when they were driving.
Taking the whole thing together, I think it might well be the case that the sunglasses guy was trying to engineer a punch-up, so that he could turn it into a lawsuit and publicity circus.
