True story, I met an old, retired CIA spook at a wedding. Dude looked like Col. Sanders, down to having the white suit. So I asked him:
"I don't want you to tell me anything you're not supposed to tell me, but when Kennedy got killed, what was the talk around the water cooler?"
"Oh, hell, we all thought Johnson did it."
No pause, no thoughtful chin rubbing. "We all thought Johnson did it."
