Why did Dantes want to see the governor the first time he came to Chateau D'if? (2)

Dantes wanted to see the Governor to ask why he was taken to the Chateau, as he had not committed a political crime.

“I am not going there to be imprisoned,” said Dantès; “it is only used for political prisoners. I have committed no crime. Are there any magistrates or judges at the Château d’If?”
