Why is Jeanette so fascinated by newspapers?

Jeannette is fascinated because for the first time in her life she can understand what is happening in the world around her.

Because we never subscribed to newspapers or magazines, I'd never known what was going on in the world, except for the skewed version of events we got from Mom and Dad—one in which every politician was a crook, every cop was a thug, and every criminal had been framed. I began to feel like I was getting the whole story for the first time, that I was being handed the missing pieces to the puzzle, and the world was making a little more sense.
