To investigate the implications of source selection, three different sources regarding Guatemalan state terror are compared: newspapers, human rights documents, and interviews with eyewitnesses. Results show that each source pays attention to diverse types and aspects of repression in line with the objectives of the observer, the characteristics of the repressive events, and the overall political context within which events take place. Who is consulted influences what is observed/recorded. Suggestions are presented for understanding sociopolitical behavior through diverse data sources, especially behavior related to contentious activity and/or occurring within contexts that are not easily penetrable.
