Bro, I have seen investigators take discrepancies between witness testimony - we're talking an entire year and states apart - and wave it away with, "Well, we know what they really meant to say was..."
And the adjudicating authorities accept it because those are the investigators. If you can't implicitly trust them, the whole system is jeopardized! Durr! Durr! Durr!
I'm not surprised; I'm just hateful all over again.
