Posing with the murder weapons while looking like some type of political loon has that impact. Another example of arguing that the evidence against Oswald is so overwhelming that it can only mean he is innocent. LOL.
The problem with the photos is not that they showed a unstable crackpot posing like this - look at this guy! - no the problem is that news magazines ran the photos and poisoned opinion against him.
Suggestion: if you don't want people to think you're an unstable person then don't pose for photos that make you look like an unstable person.
Poor Oswald. Everybody was against him. Steam fitters, waitresses, warehouse workers, cab drivers, secretaries, shoe salesmen, ticket takers, used car salesmen.......No wonder the guy didn't like America - we were all out to get him.
