a lot of study and analysis including what happens to all the u.s. military hardware left behind. clarissa just mentioned a video that provides a stark answer tonight. it was shot reportedly just after the last u.s. flight left. l.a. times journalist took the video walking behind taliban fighters who were wearing, clearly, what seems to be u.s. supplied gear, carrying american m-4 weapons, walking toward what was just before a u.s. helicopter. it is now in the taliban hands. i spoke with them just a few minutes before air time. explain when you shot this video and and what it is we re we re seeing. what happened here? so we took this video minutes after the last american plane had left. at that point, you had the taliban sort of around the sides of the airport. and then, when they saw there were no more planes, they waited a bit and then went inside, en masse. to go towards the gate.
