Justice can be impossible  The Rwandan genocide one of the largest the world has ever seen since the Second World War. A large number of victims – at least half a million – means a large number of perpetrators. There are 100,000 alleged perpetrators in Uganda. While an informal Gacaca system has been criticized by human rights groups for not being able to provide fair trials, a full system of fair trials would be impractical [1] .  Rwanda is now relatively peaceful, with a functioning economy.  [1] Hannum, p492
