These are clips from an interview and a lecture both by Gavin de Becker, the leading US security expert. The first pair are a 9/11 appearance on The Late Show with Craig Ferguson in which he talks about the TSA and terrorism, and the second set is a talk he presented to the Symposium on Federal Architecture.
He’s a good speaker, and obviously he knows security. The thing is, people generally find sound secure thinking counter-intuitive until they learn (and ideally internalize) some basics. Then the realities and mechanics and such make sense, and when that happens we’re not so easily manipulated through fear.
