question:  What crime has Zeckler committed to warrant imprisonment?
context: There was a startled gasp from within, and a skinny, gnarled little man suddenly appeared in the guard's light, like a grotesque, twisted ghost out of the blackness.

They've built up the most confusing and impossible system of barter and trade imaginable, aimed at individual survival, with land as the value behind the credit. Lying is the time-honored tradition, with their entire legal system built around it." They have only the haziest idea what truth represents, and they've shrugged off the idea as impossible and useless." Encroachment on private property is legal grounds for murder on this planet, and twelve of them descended on the same chunk of land at the same time, all armed with title-deeds."
