Pedro Martínez: Like I said, the guy is an idiot then... you dont have to be a clairvoyant, just know what an average person under average situation should do....

If I am trying to walk my way home from work, and that is my sole agenda, and there are a gang of police in full riot gear, and you are in a known volatile area, most prudent people would figure out a way to stay out of the way... find a different route or move a bit faster or whatever it would take... a prudent person would not likely just stroll along with hands in pockets like that in a close proximity to the police.... as far as i know too, the police dont like people with hands hiden like that, they get wary that a gun or hand grenade or something might come into play....

Again, the UK is probably different, but here in the police state of the US, that is our standard of proof, what would a normal prudent person be expected to do or how would they behave in a given situation?

The guy might only be guilty of being an idiot... and the police is only guilty of being an idiot too....
