Brian Palmer is a veteran journalist and foreign correspondent. He embedded with the First Battalion/Second Marines three times between 2004 and 2006. He's now made a documentary film called "Full Disclosure," about the experience. He tells Anne Strainchamps that too much embedded reportage becomes cheerleading for new weapons systems; and that he still doesn't know how to strike the right balance between photographing the truth of war and respecting the families of the fallen.
