How does John Grisham use imagery in The Client?

Imagery:

"He threw her outside, completely naked, and dragged her into the street where, of course, the neighbors were watching. Then he laughed at her, and left her lying there."

"The mafia is an invisible army with plenty of soldiers."

"The tough little boy who threw rocks through windows and outsmarted killers and cops and raced fearlessly through dark woods began to cry."
