>> look at this photo taken just seconds after the gunshot. it shows police rushing out of the firehouse. you can see the roof. there's no one up there. so if the army intelligence agents were not on the roof at the fatal moment, then there could be no photograph of a shooter in the bushes, despite what pepper wants to believe. we have seen the army intelligence unit's records on what it did do in memphis. those files say the first photos the agents took were not until coretta scott king led a memorial march in memphis. four days after her husband's death. that leaves the uncertain story of jim's grill and its owner, lloyd jowers. >> he was usually drunk. of course, that place was a hole in the wall, cockroaches everywhere.
