Climate Camp 2009 organisers say police have a history of violence and intimidation against peaceful protesters and the best thing for the public's safety would be for officers to stay away. Activists themselves will not receive texts revealing the location of the mini-community until the last minute. In an open letter to Scotland Yard today, organisers wrote: "I'm afraid we just don't trust the police. It seems every time we have a protest, they turn up and start hitting people."
