Would you rather he was arrested for obstruction?
It's about time that people realised that when given a lawful order by a Police Officer that they should actually comply with it. Having been asked to move back several times and ignoring the polite requests from two seargents and one inspector he thought that he would simply ignore them and carry on? The Police are trying to control a fairly volatile situation there and the inspector had it right when he said "cover it by all means, but from over there" It's a public order situation and his to control. The Seargent also told them to stay on the pavement and not block the road. Again, a lawful order.
Two wrongs don't make a right and the PC in the fluorescent jacket was out of order when he said he could not be filmed, of course he can and some re-education is definately required there. But the journalists do themselves no credit by ingoring the instruction of the officers in the first place and could quite easily have been arrested for obstruction of a Police officer or even obstruction of a public highway if you want to get picky. The only problem with doing that is that it takes away the resources from where the Police are actually needed.
Sorry, but I have little sympathy.
