You are being taken down the rabbit hole by a contrarian. It's hopeless. Here is how it goes. Every piece of evidence is examined in a vacuum as though it can't be judged in the full context of all the facts and evidence. So if Oswald makes an unexpected trip to the Paine residence (where he kept his rifle) and left his wedding ring for the first and only time in his marriage along with a large amount of money, this can be dismissed out of hand by a contrarian as having no relevance toward proving Oswald was the assassin. Other men have left taken off their wedding rings and left money with their wife who didn't assassinate the president. But how many men who left their wedding rings and cash with their wives that morning worked in the very building from which shots were fired? How many carried a long bag to work? How many left their prints on the SN boxes? How many left their rifle on the floor from which the shots were fired? How many fled the TSBD, got a gun, and killed a pistol officer? And on and on. But a lazy contrarian can just ignore all the surrounding circumstances and just dismiss every individual piece of evidence with LOL.
Yes, but he's not a contrarian, someone arguing just for the joy of arguing and for no other purpose. That's a contrarian to me. He has a purpose: he's an Oswald defender. It's a weird Oswald-as-Dreyfus view.
Of course no one looks at an event, reconstructs it, by looking at one piece of information alone. And ignoring all of the other pieces. You look at them in their totality and not as isolated blocks. If you applied this type of thinking to any other event then it would be impossible to come to any conclusion as to what happened. Everything saying "X" occurred can be isolated and dismissed as just random events. Poof, event "X" disappears, it never happens.
