If they were just taking pictures and asking for badges, of course not. But I don't see how we can possibly remove it out of the context though. It was 7 day long siege which resulted in 50 arrests, court cases and something to the tune of few mln £s of claimed damages to the power plant and equipment. Let's make it absolutely clear. 600 people, are trying to force their way into the power plant. Against court injunction. For all intents and purposes, just about anywhere outside Britain it would be referred to as active act of domestic terrorism. And you have some dumbo going around asking police forces for ID (which, just for the record, again, just about anywhere outside Britain would be either armed, or in full anti-riot uniforms and equipment). Leaving the grotesque surreal element to this situation of what is some vigilantes against police surveillance doing in the middle of siege and possible riots surveilling police - at what point do you expect Police to be lighthearted and bemused by their situation and duty at the given time and place enough to get into casual "Hi I'm P.C. Johny, number XXXX, I was recalled from my holiday and dragged here from East Sussex at 5am to keep an eye on these, here "activistist" actively activating their active actions and protesting their protests, and how is your day?" with what appears to be, for the lack of better description, some random Cornish dumbo with a chip on her shoulder and a notepad and her photo trigger happy friend. It's not like they are journalists in a "press" labeled Toyota following UN peace keepers.
