"Protection be on us," said Father, and he hit the button of the Cistern of Tranquility.
Flush began the service, and flush ended the service.
Father placed the Cistern of Tranquility on the balcony, in accordance to Legislation 643321 where each family was to proclaim their religion. There was no fear of conflicts, because Legislation 643330 demanded full tolerance of its inhabitants for religion.

On a randomly chosen evening, the Cistern of Tranquility fell off the balcony, plummeted some 237 floors and impaled a passing man, pipes and all.
(At this point, you can take it that the probability of him getting impaled as 0.5 (50%-50%) OR wreck your brains trying to figure out the probability of it happening with all the coincidences of wind direction, speed and etc OR say the probability was 1(100%) because of Fate)
This man died instantly.
That family (none of them wanted to testify who placed the Cistern that day, the beauty of family love) was tried and executed in accordance to Lex Talionis. A Physicist was dispatched in order not to waste too many Cisterns; this retributive justice took as much from the State's coffers.

This man that died, he was on his way to kill the Psychic Seer of the South that lived floors below that family.
The Psychic Seer of the South (worked for the State to Scry for wrongdoers) had testified against this man of adultery; justice made him less of a man.
Due to some unforeseen complexity of this man's mind, he had decided on that randomly chosen evening to kill him.
Most unfortunately, he did not have a chance.

P.S. The two Cisterns that were harmed in this fiction were refired and dispatched to two new families for worship.
