99% of the police are sound, 1% are not fit to put on the uniform, same with soldiers, nurses, protesters, etc, etc. What annoys me is the general level of anger towards the police, half the crap is not their fault, they do not choose to be under resourced, forced to fill out a pile of paper work and do the job with one hand tied behind their backs. Don’t get me wrong, if they go above and beyond the law then they like us all should answer to it. I hope justice is done in this case, I have seen video clips where it looks like your man was being a pain and getting in the way of the Police. I have seen other stills and video where he looks like Joe Public going about his business.
Others have said it before but I will too, we are lucky to have the Police that we have, pretty much anywhere else on the planet and it would have been water cannons and tear gas at the first sniff of trouble.
