How were the managers of Camp Green Lake’s sense of authority, security, and freedom challenged in Holes?

The managers at Camp Greenlake have many of their values challenged by Stanley and Hector in Holes. Stanley explicitly questions their authority by questioning their methodology, wondering how digging holes was supposed to help their improvement from criminal activities and what the purpose of this activity was.
Their freedom is challenged when Stanley and Hector return from their excursion into the desert with the treasure chest buried by Kate Bartlett. Their actions and authority were called into question by Stanley's legal counsel, and they were eventually arrested and imprisoned for their deeds. In this way, their security is also threatened, but in a broader sense, the security of the camp is threatened before that. When it was revealed that Stanley can escape and survive in the desert, the security of the camp managers is questioned, because he and Hector can potentially go to the authorities with what they witnessed and experienced.
