I am touched by the look of German policemen. It seems to me that here in Germany they really serve the public order. A conversation with a German police officer — which I engage in at every opportunity — can be seen as a form of cultural engagement.
Russian rules of communication with the police officer are as follows: answer all questions briefly and correctly, reduce contact to a minimum, never start the first conversation.
One of my German friends came up with a paradoxical formula:
Moscow is safer than Paris or New York.
Police are really dangerous here.
