That's a very complicated question. I appreciate the question.
Concerning the gacaca courts, in the Rwandan culture we have always had a situation whereby, if a conflict arises between two parties, the village comes together, and you sit and you resolve the issue. Because there were so many perpetrators and so many victims, on a communal level it was effective. Just as with any justice system, there is always room for improvement, because you rely on witnesses and what people bring on the ground.
With regard to the Congolese refugees issue, that is a very complicated issue that I am grappling with myself. I am doing my best to find information, but it is a complicated issue that might need more preparation to answer.
