where the center of everything really is? the center of the chaos is at the airport. that's because that is the only way out for thousands and thousands of americans and our afghan allies, desperate to escape. but it's so hard to get there. it's so hard to get through those crowds. some people are just giving up, at this point. sources telling cnn some who made it into the airport were bloody. they were distraught. and they lost most of their belongings along the way. one afghan who worked at the u.s. embassy for years telling cnn, quote, i decided i would rather the taliban shoot me in the head, to being stuck in that situation. the videos from the airport show just how desperate the situation is. crowds of people hoping against hope to get on a plane. gunfire heard repeatedly. you just saw it there. though the taliban didn't appear to be shooting at people. a woman today pulled over a wall -- pulled over a wall by u.s. troops.
