So…they wanted him to take a polygraph interview regarding the nature of his relationship with Peter Strzok, and he resigned instead, did I understand that correctly?
They informed him of an intent to demote him if he remained in the FBI, even taking the polygraph. The alternative to demotion was to resign. So he resigned, and now he's speaking out about it.
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.
Why go through the stress and performative dance of a poly when there's zero upside? He admitted to being a friend and (according to the article) that's alone enough to demote and block advancement.
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.
