Felicien Kabuga, a Rwandan fugitive who allegedly planned, financed, and executed one of the worst genocides in recent history, has been arrested.

Who could imagine that a man wanted by a UN tribunal, powerful governments, Interpol, and the government of Rwanda would be arrested in France on Saturday -- two decades after an arrest warrant was issued?

Genocide left a million dead

Kabuga equipped the Interahamwe youth militia, the Hutu group whose members would be among the main perpetrators of the Rwandan genocide, and used his companies to import vast quantities of machetes from China, according to financial documents found in Kigali.

It gives confidence to genocide survivors that all monsters will one day have their day in court and that they will never find a safe haven where they are safe from justice.

If they are unable or unwilling to do so, then the suspects should be extradited to the home countries to face justice and the victims still struggling to come to terms with the genocide.
