How does Nelson DeMille use imagery in The Talbot Odyssey?

Examples of Imagery:

"'There are basically five ways to hunt - baiting, trapping, stakeouts, beating the bush, and decoying. It depends on the animal you're after, the season of the year, and the terrain. With the human animal, you can use all methods, or combination of methods, in any season and terrain. Just keep in mind that when the human animal approaches, he may take any form, including the guise of a friendly animal. He may wave a cheery hello, or ask for a cigarette. But you must realize that you are being attacked, and in that split second of realization you have to act, because a second later it's too late.'"
Chapter 35, pg. 260

"'Picture a psychiatrist trying to cure a lion of his nasty habit of ripping living things apart. The lion is confused. His behavior is instinctive. The lion does not believe he's nuts. And he isn't. He's a lion, doing his thing. And if he'd been raised in a penthouse on Park Avenue, it would make no difference in his behavior. If you dropped in to chat with him when he was hungry or cross about something, he'd rip you apart and not lose any sleep over it. Lions are not guilty of murder, and some people with strong killing instincts are not guilty either. Nonetheless, a bullet in the heart is the correct way to deal with dangerous animals.'"
