Back in their room, he tells Jackie, "You know, we're heading into nut country today."
"Last night would have been a hell of a night to [redacted] a President. There was the rain and the night and we were getting jostled. Suppose a man had a pistol in a briefcase?"

Far-right Gen. Edwin Walker leaves Dallas so he won't get the blame should "something happen."

JFK confides in Jackie, "If somebody wants to shoot me from a window with a rifle, nobody can stop it, so why worry about it?"

There are jokes among the city's well-to-do families that someone should take the opportunity to shoot JFK in the head.

No way any of this is real. This is way too on the nose. Are there any sources for these quotes?
