The media is making a big hubbub out of a videotape of a Marine killing an apparently wounded insurgent who appears to be faking death. Buried in the CNN story is a fact that has a significant impact on why the Marine might have behaved with an excess of caution.

About a block away, a Marine was killed and five others wounded by a booby-trapped body they found in a house after a shootout with insurgents.

If in doubt, shoot.
