Why does the author revert to phonetic spellings in certain sections of the book, The Free-Lance Pallbearers?

Reed often uses phonetic spellings instead of standard spellings, capitalization for emphasis, and uses news flashes and radio voice-overs to comment on the book's action. The effect is a narrative that reads much like a motion picture or television show. The pacing and flow are reminiscent of the way the media communicates its ideas.
