Someone ground down and dehumanized by a corrupt bureaucracy. The modern judicial systems largely use adversarial processes as a proxy or as an approximation of truth. There are no oracles of truth. No one is your friend. There are only people trying to win, and this will inevitably include gaming the system. The DA is no one's friend, even if you are the victim. The cops aren't your friend. Everyone just wants to win. This is why there is the presumption of innocence and the 5th amendment.

EDIT: This sort of adversarial judicial system is akin to Democracy, in that it's the worst system of its type, except for every other system we've tried.
