With all the rumours that bin Laden got typhoid and has died, I do not feel like it has been some kind of victory. Indeed, if he is dead, then he has died the death of Mengele. Joseph Mengele, the Nazi concentration camp monster died an accidental death in Brazil.
So yes, Mengele died, good riddance, but, uh, we all do. Mengele was never brought to trial and never had to give any account of himself to the world. If bin Laden has died, he has died the same kind of death, never brought to justice.
