Earlier quoted context omitted.
He was a senior G-man. He knows the polygraph is bullshit.
True, but you also have former agents who complain that they get fired for things w/o having taken a poly. So, it seems, for some, passing a poly as proof they don’t do something wrong is important.
Polys are also subjective. They keep asking the same questions over and over again until there's some indication they can point to and say you're lying. It might be a sneeze, cough, or a deep breath at the wrong time. It's also generally a multi hour to multi day ordeal. I wouldn't bother if I was them.
