Thanks. I didn't realise the guy went in with a gun. Still, it's fascinating how absolutely he turned around once he didn't find anything. He clearly wasn't delusional, since delusional people are not affected by incontrovertible*, evidence against their delusions. The delusion simply morphs to accomodate new evidence, or the evidence is hallucinated/confabulated away. *It has to be truly incontrovertible, though. E.g someone who continues to believe they can fly despite numerous failed attempts.
