Sam Harris addresses your criticism on his web site at this link response to controversy. I actually would like to get into this discussion a little more, but I am going away on Wednesday and access to a computer I can't count on. Perhaps when I get back, at this point not sure how long that will be. I thought the majority of Hedges presentation was utter nonsense. Some of that nonsense, Sam Harris addresses here at this link Sam Harris fights back
But back to your criticism of Harris's position on killing people, he doesn't believe there are ethical reasons to kill based on religious beliefs but based on behaviors/potential behaviors of which some are fueled by religious beliefs...in some cases. It's a cold cruel world, in which the lesser of evils often must be chosen. It is sometimes a matter of kill or be killed and hence it can be considered ethical in some situations to kill.

Same Harris writes:
My discussion of killing people “for what they believe” (pages 52-53 of The End of Faith):
The following passage seems to have been selectively quoted, and misconstrued, more than any I have written:
The link between belief and behavior raises the stakes considerably. Some propositions are so dangerous that it may even be ethical to kill people for believing them. This may seem an extraordinary claim, but it merely enunciates an ordinary fact about the world in which we live. Certain beliefs place their adherents beyond the reach of every peaceful means of persuasion, while inspiring them to commit acts of extraordinary violence against others. There is, in fact, no talking to some people. If they cannot be captured, and they often cannot, otherwise tolerant people may be justified in killing them in self-defense. This is what the United States attempted in Afghanistan, and it is what we and other Western powers are bound to attempt, at an even greater cost to ourselves and to innocents abroad, elsewhere in the Muslim world. We will continue to spill blood in what is, at bottom, a war of ideas.
This paragraph appears after a long discussion of the role that belief plays in governing human behavior, and it should be read in that context. Some critics have interpreted the second sentence of this passage to mean that I advocate simply killing religious people for their beliefs. Granted, I made the job of misinterpreting me easier than it might have been, but such a reading remains a frank distortion of my views. Read in context, it should be clear that I am not at all ignoring the link between belief and behavior. The fact that belief determines behavior is what makes certain beliefs so dangerous.
When one asks why it would be ethical to drop a bomb on Osama bin Laden or Ayman Al Zawahiri, the answer cannot be, “because they have killed so many people in the past.” These men haven’t, to my knowledge, killed anyone personally. However, they are likely to get a lot of innocent people killed because of what they and their followers believe about jihad, martyrdom, the ascendancy of Islam, etc. As I argued in The End of Faith, a willingness to take preventative action against a dangerous enemy is compatible with being against the death penalty (which I am). Whenever we can capture and imprison jihadists, we should. But in most cases this is impossible.
