How does James Patterson use imagery in Season of the Machete?

Imagery:

"The Philadelphia doorman had found a bloody machete driving halfway to China in the sand. He'd found the two hippies who had been killed and mutilated by the Cuban and Kingfish Toone. And so had a hungry band of wild goats."

"Here you finally make time for a vacation. You pay over two thousand, say, for ten glorious days of not having to schlepp around Manhattan with all the gum snappers, panhandlers, the general roll call of sewer snipes ... And then suddenly, slam-bam, you don't just get a little rain to ruin your good time ... You don't get a sunburn ... You get a bloody revolution."
