Mr Schwennicke, a journalist with a Munich paper who had been posted to London, said: "I want to do what I can to give people a wakeup call. To tell people, 'Listen, I had this experience. I find this system dangerous and you should consider changing something'. As a journalist I am used to judging things maybe too quickly, but this time I've thought a lot about it and I would like to tell you, something is not in order here."
