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 thecontemporary 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.

We could describe this threat as a state that produces feelings of fear and insecurity upon a subject. A state with input and output that feeds itself and in its turn feeds, affects and leads to action. The threat is born in the city, in its dark passages, the announcements in the subway, the police patrols, the sight of strangers, breeding fear in its turn.

However the urban’s environment heterogeneity doesn’t allow us to speak of particular subjects. The roles constantly change: the one who produces fear may be stranger, neighbor,or agent of power… Fear constantly changes sides; being flexible it can jump form one social group to another. It is other people we are afraid of, and other people are those who are not we, this moment, the moment of fear.
