Surrounded by an insecure urban environment, one thing we can be certain about is that it has become a threatening place. This is probably one of the few features of the contemporary city we can be sure of, in our endless effort to determine its identity. It is a threatening, liquid and obscure environment. The threat in the city is as liquid as the city itself. The threat is there, it spreads itself in various ways and, like a well-designed product, manages to reach the most distant places. And there, naturally, it affects, transforms and shapes peoples’ attitudes.
