While I think that anger can be valuable, and channeled productively, there's a line that has to be drawn. We have systems, courts, and basic reason to temper our urges for revenge. That's why we seek justice, not revenge.

It's an interesting article, but a very slippery slope. Human rights apply to everyone. Humans make mistakes, and who are we to dispense the 'ultimate justice' and who wants to live in a world where we are motivated not out of understanding about what right and wrong is, but simply by fear? It sounds like a police state to me. We might as well live in the stone age if we want to be ruled by our outrage at every turn. Very good food for thought, though.
