How Should Jews Respond to Bin Laden's Death?

A friend of mine forwarded me this link which provides an interesting approach on what the Jewish reaction should be to Bin Laden's death. How should we respond to the deaths of our enemies? Is it ever correct to rejoice at the death of another person? We know that on Pesach, even when commemorating our victory over those who enslaved us for hundreds of years, we still spill out drops of wine from our cup while listing the Makkot and omit parts of Hallel on the last days of Pesach (when the Egyptian army drowned in the sea) out of respect for the Egyptians' suffering. So how should we react to yesterday's news of Bin Laden's death? Check out the link and think about it!
