Police state UK...I was arrested for walking down a London street because I was eating an ice-cream...It beggars belief

Indeed, I was walking down the street minding my own business when all of a sudden I was surrounded by the long arm of the law. They arrested me for 'breech of the peace'...Eating an ice-cream is now breach of the peace in police state UK. The police tried to make excuses mumbling something about...'that is not an ice-cream it is a can of super strength cider and you have no trousers on'. Well, I was back affronted, as I clearly mentioned in a previous post a man at the pub was sick down my shirt and had pished and shat in my trousers and I was just trying to dry them off....I thought they would have understood but there is no reasoning with the police in a police state. Thoughts.
