...and I probably should have added to my post to tie it all together, clarify, and get back to the original topic, that in the case of this photographer, the fact that he was white, male, middle/upper class in the UK didn't spare him from being harassed by police, as in no preferential treatment here.
Marko: IMO - this might be a pure policy issue (having cops harass the occasional photographer in a public place). PERHAPS they feel that if the public sees cops checking people out (and arresting them) the public will feel safer.
I'll watch the 2nd one later, but that 1st one that started this thread, to me, just seemed to be a random situation that developed when a photographer attracted attention, wrong place/wrong time, and a cop a bit high on authority and low on judgement asked for some info, and as soon as the guy "resisted" authority, it all went to hell in a handbasket from there.
