Have to say, I've heard that, due to all the CCTV cameras, the Police are keeping on top of street crime in London. But I've no idea what goes on after dark. Bad things probably! Paris is beset by street children who come up begging and grab your bag. Have done a short study course on Crime in London throughout the ages, and it's amazing how things don't change. Drunkeness, thieves, pickpockets, beggars, congestion (horsedrawn of course!) Any big city is bound to be the same.
