Several readers pointed out that in real life FBI Director Freeh had been gone for a few months, and that Mueller was in at the FBI by a week or two. That doesn't work out so well for me firing people off. Therefore, we are holding onto Freeh for a few months longer, and that got written into the story.
The reader who reminded me of Asimov's Foundation made me curious, so I spent a couple of nights rereading my well-worn copy. The reader attributed the quote ("Never let your sense of morals stand in the way of doing what's right.") to the character Hober Mallow, but that didn't seem right to me. It was actually said by the character Salvor Hardin, who had other pithy comments credited to him. Others which might prove helpful to Carl would be: "Violence is the last refuge of the incompetent.", "An atom-blaster is a good weapon, but it can point both ways.", and "It pays to be obvious, especially if you have a reputation for subtlety."
