Just look at this photo, next to THAT DOOR – plus, and this is a big plus {as compared to the police in Zimbabwe} that smiling, happy policeman behind them – he is the thoughtful chap who took many of the photographs within the secure compound surrounding the Offices of the Prime Minister. He was there to ESCORT the 6 Petitioners around the entrance to 10 Downing Street – in this regard – more like a guide – a friendly guide!
