The circle surrounding Arc de Triomphe is an amazing cluster of vehicles going in several different directions all at once. This photo is typical of what is happening in the entire circle at any moment, with the sounds of brakes squealing every couple of minutes. Several of these police officers, who apparently angered someone at some point or other, have the unattractive task of standing right out in the middle of it trying to make some sense of it.
