Or maybe they think they are taking it back when on a jury? I've noticed that they seem to act as if the State is always trying to pin something on an innocent person, like they automatically distrust the State very much and want to find any way the defendant must be being scr#wed. Perhaps it's projection. They are paranoid about being scr#wed by the State themselves, imho.
I lived in a former Soviet Block country right after Sovietism fell there. It's amazing (but understandable) how the paranoia can creep in and color views of situations that have nothing to do with what the person is actually afraid of (the State, there)

The people at my plant had weird conspiracy theories about our yarn suppliers, lol
