"At some airports" is as confusing as saying most of them probably do record sound. Whether they have a right to do it and inform us that they are doing it or they are not doing it or doing it illegally (meaning they can't use it in hte court of law unless actual prevention of an imminent and direct attack is prevent right at the moment.)
