old techniques are the best way to do it dead drops, brush passes. >> a dred drop is where you put something like on the ground what lan son did, you bury something, they get it and put money someplace else for you. that's a dead drop. if you're disciplined and follow your trade craft like hansen did for years and years, it's almost impossible to catch them without a source of information from somewhere else. what happens is after they've been here for a long type, they have kids and they get tired, and all that wears away at the discipline. >> you know, i was finding out the other day, my father's in intelligence in philly and i didn't think he had a very exciting job but somebody dug this up, he was sitting there with a newspaper spying on somebody in intelligence. like looking through the hole in the newspaper. this stuff. your thoughts, jack? did you discover anything that was new here in the trade craft of spies besides having a beautiful woman as your lure? >> well, you know what? that has always worked very well
