Horrigan: For years, I've been listening to all these idiots on barstools with all their pet theories on Dallas. How it was the Cubans, or the C.I.A, or the white supremacists, or the Mob. Whether there was one weapon, or whether there was five. None of that's meant too much to me. But Leary, he questioned whether I had the guts to take that fatal bullet. God, that was a beautiful day. The sun was out, been raining all morning, the air was... First shot, sounded like a firecracker. I looked over, I saw him, I could tell he was hit. I don't know why I didn't react. I should have reacted. I should have been running flat out. I just couldn't believe it. If only I'd reacted, I could have taken that shot. And that would have been all right with me.
Mitch Leary: What did happen to you that day? Only one agent reacted to the gunfire, and you were closer to Kennedy than he was. You must have looked up at the window of the Texas Book Depository, but you didn't react. Late at night, when the demons come, do you see the rifle coming out of that window, or do you see Kennedy's head being blown apart? If you'd reacted to that first shot, could you have gotten there in time to stop the big bullet? And if you had - that could've been your head being blown apart. Do you wish you'd succeeded, Frank? Or is life too precious?
Mitch Leary: Do you have any idea what I've done for God and country? Some pretty fucking horrible things! I don't even remember who I was before they sunk their claws into me!
Raines: I heard you and Nixon didn't get along.
Horrigan: Now, that's not true. His chief of staff, though, that was a different story. I remember one time, he wanted me to go out and get rid of some anti-war protesters. I said no, talking about the Bill of Rights and so on. And he says, "look, when I'm talking to you, I am the President." I said, "The President? That's funny, you look more like a sack of shit in a cheap suit to me, sir!"
Frank Horrigan: You're looking at a living legend, Lilly. The only active agent who ever lost a president.
