Urban “disorder” has been treated as a characteristic of the ambiguous nature of large cities. But recently with the broken window theory and related policies becoming dominant worldwide, disorder has come to bee seen as mere “problem” that should be eliminated. This paper examines ambiguity of urban visible disorder. For this purpose, I took as a case study a local patrol directed against street pimps conducting interviews and participant observation. I found that street pimps and patrol members got acquainted over the years with a consequent change in their mutual relations. I conclude that in making guests available to sex industry shops that are invisible from the outside the visibility of street pimps makes them simultaneously both “nuisance” and “mediator”.
