This guy flew nuclear bombers for a living. The military has (sorry… used to have) a special vetting process for those guys.

I am sure when he was arrested for this crime, the USAF chain of command from top down and back up again asked themselves “How did this guy slip through the cracks, how could we have seen this coming, and how do we modify our screening process to make sure we never again bring a pilot with his flaws into our ranks?”

In other words, how do we reduce the threat to zero?

Not JetBlue. They just ask “What are the odds this guy will snap a second time? Less than 50/50? Hired!”
