I wondered whether K’s original crime was being “the sort of person who would express excessive pride before the law” - a Minority Report style “Contempt of Court”.
I've always been wondering if the crime matters at all. A lot of people say that going through a trial, even as a victim, is a punishment; it's the process that counts (hence "der prozess"). Perhaps the lack of a stated crime reflects that we the general public never fully understand under which specific provisions someone gets locked up. And so the actual deed may have been done before K. was born, etc.
