a kalashnikov, a luger pistol, plus nearly 300 rounds of ammunition. in his bag, a half liter of gasoline. authorities say el khazzani initially told them he just wanted to rob the train, having found a bag full of weapons in the park. the three americans who tackled him enjoying the fruits of their fame. last night anthony sadler on the red carpet of the paris premiere of "straight outta compton." >> this is unreal. two days ago we were on the train and now all this has happened. this is crazy. >> reporter: his two friends receiving hospital treatment at a military hospital, still haunted by that confrontation on the train. the fourth american hero is still in intensive care. as for the case against el khazzani, it's still in its early stages but if convicted he could face life in prison. george? >> david, thanks very much. another story developing right now, caroline kennedy facing questions. the u.s. ambassador to japan criticizing for using a private e-mail server for public
