Marking bourdaries as a strategy of social control: the case of homicidal violence in Medellin, Colombia.

As part of a research study undertaken in the period 2003-2011 to understand situations of homicidal violence based in perceptions regarding the act of violence and the surrounding context, we reflect on the meaning of "invisible bourdaries" in the neighborhoods of Medellin (Colombia). Using a qualitative approach that combines documentary sources and interviews, the experiences of 8 participants are analyzed. In the primary results we can see how control over neighborhoods is exercised by different actors through bourdaries not visible to ordinary people.
