“It’s no use, Your Honor,” K. continued, “even your little notebook confirms what I’m saying.” Pleased that his own calm words alone were to be heard in that strange assembly, K. even dared to snatch the notebook from the magistrate’s hands and lift it in his fingertips by a single center page, as if he were repelled by it, so that the foxed and spotted leaves filled with closely spaced script hung down on both sides. “These are the records of the examining magistrate,” he said, letting the notebook drop to the table. “Just keep reading through them, Your Honor, I really have nothing to fear from this account book, although it’s closed to me, since I can barely stand to touch it with the tips of two fingers.” It could only be a sign of deep humiliation, or at least so it seemed, that the examining magistrate took the notebook from where it had fallen on the table, tried to put it to rights somewhat, and lifted it to read again.
This entire paragraph confuses me on how to court proceedings work, how is K allowed to interrupt and mock the magistrate? Are there not guards and other people there to keep him in check? Why is he allowed to call the magistrate a liar and practically tell him he is wrong?
