(38) Oswald was the sole owner of the revolver found in his possession on arrest.

It's possible... I find the evidence that Oswald owned a pistol far stronger and more credible than that for the Mannlicher Carcano. But owning a pistol that wasn't used to shoot JFK and could not be ballistically matched by the FBI for the Tippit murder is just as credible evidence against Oswald as the thousands of other people in Dallas that day who owned a pistol.

Indeed, the police arresting Oswald all had pistols. The mere possession of a legally owned firearm has never been 'proof' that someone committed a crime.
