It's the old question: Do you take Hitler out after that Nuremburg rally? We got intelligence reporting that this guy was scouting out advanced reporting. We need to preserve the methods and sources of that intelligence, ESPECIALLY in time of war, which this is.
And you don't win wars by coddling the enemy. You win wars by taking them out of the picture, either via capture or by having them assume the ambient temperature atthe hands of our military forces. Any questions?
