Yes I'm under no illusions that they aren't all bastards, which is why I said "But really we don’t know to what extent they illegally withhold stuff.", and prefaced it with "technically".

Of course they lie, cheat, and make the process harder. Though once in a while FOIA requests turn up something juicy despite all that. I suppose it depends on how much it harms the pigs or the system as a whole to release it.
