How does Hugh Laurie use imagery in The Gun Seller?

Imagery:

"I had been shot, beaten, knocked off my bike, imprisoned, lied to, threatened, slept with, patronized, and made to shoot at people I'd never met. I had risked my life for months, and was hours away from having to risk it again, along with a lot of other lives, some of which belonged to people I quite liked."

"A helicopter that is smaller, faster, and better-armed than anything you have ever seen in your lives. It is going to come here, very soon, and take us all off the roof of this building. It is probably going to take the roof as well, and the next two floors, because this is a machine of unbelievable power."

"The Sword Of Justice is, in reality, being financed by a western arms dealer, in conjunction with renegade elements of the American CIA."
