As a documentary filmmaker, I'm very respectful, and my interview style is not intrusive. I don't really have an agenda. I just go in there, I mumble something or other, I wait for them to speak, and I wait for them to stop.
Espionage, for the most part, involves finding a person who knows something or has something that you can induce them secretly to give to you. That almost always involves a betrayal of trust.
