Of course Chapman would find some way to try to discredit Craig, since he was a dedicated and thorough law enforcement official. Craig reported several things that are inconvenient to the lone nutters. Recall how he carefully describes finding the Mauser, how Weitzmann, an expert in firearms identified the weapon and even pointed to "7.65 Mauser" printed on the barrel. Craig also saw Oswald running down the hill and entering the Rambler and led the search in the railroad yards. That's a trifecta Chapman is never going to accept. So many dishonest lone nutters...
