4. In August 2001, the International Criminal Tribunal at The Hague convicted Radislav Krstic of genocide. Krstic is a former Bosnian Serb general. International law defines genocide as "acts committed with intent to destroy, in whole or in part, a national, ethnical, racial, or religious group."
Krstic was sentenced to 46 years in prison for his role in the massacre of more than 7000 unarmed Muslim men and boys in Srebrenica in July 1995. During the trial, prosecutors presented evidence of the crime, including accounts of survivors, documents from the Bosnian military, and photos of mass graves. The three presiding judges concluded that while Krstic did not order the assault on Srebrenica, he played a key role in the executions and deportations that followed.

a. Under what class of international crimes does genocide fall?
b. What evidence did prosectors use to prove the case against Krstic?
c. Decide whether or not the sentence that Krstic received was fair. Justify your answer.
