I would not be at the wrong place at the wrong time. My behavior when I am overseas is so non-threatening that no one would ever mistake me as a hooligan. I came upon a demonstration in Rome in front of the Presidential palace. The only reason I was upset was that police were blocking me from the Roma store! I went around the demonstration. Came back to the Roma store the next day. If a policeman raised a baton to me overseas I would be backing off so fast they would have to chase me. My guess is they would have other people to worry about instead of me.
