You're assuming people make rational decisions. Lisa Nowak was both a Navy pilot and a NASA astronaut. She drove across the country in a diaper with a kidnap kit in her vehicle. Military ain't special, they're just people. Rational people consider the scrutiny that will follow when they make big public moves. I don't know if the FO is rational or not. One would like to think airlines hire rational FOs, we'd also like to think they don't hire men who become rapist captains. I think everybody can agree on those two statements, yet one of them is false in this particular case.
