It is all wrong, wrong, wrong. Your friend, Schweikert, said that it was ok to assassinate bin Laden because he was a monster. He is wrong when he said "yes" based on moral conditions. It reminds me of a moral question from long ago that I once posed to a minister when I was a new Christian–I asked if it was a sin to fornicate. His reply: yes, as long as you love the person. Right then, I knew that he was wrong. Your friend was wrong, and failed to tell the truth (like the minister) when you asked if it was ok to assassinate bin Laden.
Thank you for being the "voice of the US Constitution." I could not rejoice over bin Laden's death in spite of the fact that he was a monster.
