“You, dear readers, know my advice about talking to the FBI: don’t. If the FBI — or any law enforcement agency — asks to talk to you, say ‘No, I want to talk to my lawyer, I don’t want to talk to you,’ and repeat as necessary. Do not talk to them ‘just to see what they want.’ Do not try to ‘set the facts straight.’ Do not try to outwit them. Do not explain that you have ‘nothing to hide.’
Shut up, shut up, shut up, shut up, shut up, shut up…”

The key point is that our communication styles and habitual ways of thinking do not line up well when the focus becomes capital T “Truth”. We’re fallible human beings that frequently do not know the truth about ourselves, the world around us or even the truth about all the relevant context of events in which we take part.
Imagine, for example, the CIA operative that was involved in clandestine operations in South American countries in the 1980’s. Should this person be teaching college-level history courses based on their subject knowledge, particularly because they are acquainted with what was happening “behind the scenes”? Or, does his subjective experience compomise his ability to convey the truth in a more complete way?
I’d argue being involved in something compromises both our ability to explicitly know the truth of it, and there is also always an implicit knowledge informing our understanding that we cannot communicate in an explicit way that makes all communication false on some level.
In most social circumstances, this ambiguity and imprecision helps us all get along, allowing us to rationalize or interpret things how we wish. But, in the context of a law enforcement interview, this flexibility is how cases are built against people.
