Well I skimmed some of that, what exactly was he trying to highlight? Other than he appears to be a a rather obnoxious individual.
What a nob! I would not have gone down to him either, if I thought I was going to have a camera shoved in my face by some jumped up little wannabe journalist! They are not in the public eye. They are people trying to get on with their lives and trying to do a job. I used to stand Barnsley market for a while(and worked on it for a long time too), and I'll be the first to say that the management team who were there at the time were shocking. Most ex-traders will say the same. Now, if they are still the same then I can't imagine they have improved much. But it still doesn't mean it's ok to try and publicly humiliate them on camera. He could have easily put the camera away and spoke to the manager/representative and took notes, before reporting his findings. The trouble is, he wouldn't get all his "likes" and his ego stroked if he did it like that, would he?
For me it's one thing to film a conversation in public so you can hold someone to acocunt. It's another to film someone in public and then act like a total prat to try and provoke them. Fair play actually to everyone he confronted who I though dealt with him very well.
My 1-day online psychology certificate tells me he's 5'6, got bullied at school and didn't get hugged as a child. Getting someone to breach security then grassing them up. What a c0ck
