The “science” is NOT the issue here!
It is the POLICY!!!!
Do you have a copy of FBI POLICY regarding employees who fail their Poly?
More to the point for petty pedant tyrrants like you, like I said, if the director of the FBI did not follow his own policy, so what? It may in this case be morally reprehensible, but you cannot throw him in jail for something that is within his discretion - namely to approve exceptions to standard policy. I have a general rule, a policy, but I may vary from that as circumstances dictate.
And I am not defending the subject of this thread.
