Having just watched the video of Nick Berg being decapitated, I know the meaning of sickness, depravity, & horror. I listen to the voices of the right wing media and hear that we all need to see this so that "we understand what we are fighting". As with all things however, the devil (no pun intended) is in the details. Just who do we kill to gain justice for Nick Berg? What I seem to be hearing is "kill em all, let God sort them out". Dealing with the guilty is far easier than finding the guilty. And for every innocent person that we kill, we create 3 new potential terrorists (my estimate only). That is partly why the abuses at Abu Garib (sp.) Prison is such a big deal. While I in no way see equivalence between what we know (so far) of the Prison abuses and what happened to Mr. Berg, it is important to note that I am not the one we need to convince. There are Islamic extremists who look for any excuse to feed their hatred and we seem to be hell bent on providing it to them. And before anyone blames "the media" know full well that innocents will talk, pictures or not and the result will be the same.
So, while we need to avenge Nick Berg's murder - we need to do it judiciously and concisely, or the solution becomes worse than the disease.
