I guess it's kind of a pain [..] It would be 'kind of a pain' if the system worked so reasonably well that any remotely decent parent could trust to be acquitted within a week. As the system is, it's not just 'kind of a pain'. It's an emotionally wrecking experience, because you live in uncertainty for a long time, where the possible consequences are severe and you can't be sure of a positive outcome, no matter how decent you are. Kafka understood this.
