There are two explanations as to why the government doesn't bother those in the hobo camps:

1. According to Faber, the government doesn't bother these people because they "never considered them a great enough danger to go in and track them down."

2. According to those at the camps, they did not keep books on them, instead they kept them in their heads and destroyed whatever books they had.

He says that they're "stopped and searched occasionally, but there's nothing on our persons to incriminate us."

The hobo camps make up a loosely-based organization full of intellectuals and other book lovers. The camp Montag runs into has former professors from UCLA and Harvard and a preacher who angered the government. They memorize books with the pledge to write them down once the social order changes to one that welcomes intellectual thought.
