if you were an insider and wanted to whistleblow, but not actually go through the legal process of claiming protection, etc., wouldn't it make sense to just accidentally spill your thoughts to a hot chick?
I think of these as confessionals. they likely know or even helped set up the environment for them to give a taped confession, so that they can go back to the bosses and say they were duped.
"look, how was I supposed to know I was being taped?"
the only thing that matters is whether they hold the position they say, and what they say.
