In this article, my proposal is to reflect about my participation in a judgment against six policemen, which had happened in La Plata city in Argentina. From the point of view of my engagement as a "witness" and from the observation of the session, I had identified the confluence of three kinds of knowledge: the anthropological, the juridical and the judicial. From that distinction, it will be suggested to think about the relation between facts and law as being specific from different types of knowledge, and furthermore having different levels of legitimacy and likelihood in the judicial context. My goal is to demonstrate that, in that judgment, the anthropological, the judicial and the juridical knowledge present legal sensibilities related to the positions and interests being defended, and to the specifics actions that they represent.
