Premise: The Impuzamugambi (] , ""those with the same goal"") was a Hutu militia in Rwanda formed in 1992. Together with the Interahamwe militia, which formed earlier and had more members, the Impuzamugambi was responsible for many of the deaths of Tutsis and moderate Hutus during the Rwandan Genocide of 1994.
Hypothesis: The Impuzamugambi acted mostly alone
