I'm reminded of a scene in the movie "The Dead Zone" (Stephen King) which starred Christopher Walken, and there was a part where his doctor says "if you could go back in time and had the chance to kill Hitler (before the Holocaust began) would you?" The doctor said he would. I would too. But I get the feeling reading some of the comments in this thread, that others would be inclined to say "of course not. That would be murder."
There's no rationalizing with a premeditated murderer and worrying about THEIR rights. They gave up that option as well as their humanity when they killed innocent people. They don't play by the same set of rules as a "civilized" society. To deal with them, you have to deal with them on a level they understand, and 2 up them, in the process. I'm inclined to agree with the main points of Claymore's arguments (racial slurs aside) and the follow-up Guest's comments.
Without those willing to draw that line in the sand, the rest of us are helpless to the evil that awaits us and all the rational, civlized "compassion" in addressing it is not going to make it go away.
