We're talking his "mind" here. So don't forget, too, that he had his USMC ring on the day he was arrested.
His mind, as in: "I'm going to have my wife take photos of me holding up incriminating evidence such as a rifle and a Communist leaning newspaper. But 7 months later, because I hate all things 'Merica, I'm going to blow the president's head off...but I'll just wear my USMC ring on when I do so."
Sure, sure.
