Smullyan’s Paradox
Actually, whomever named these people are the guilty ones.
At a desert oasis, A and B decide independently to murder C. A poisons C's canteen, and later B punches a hole in it. C dies of thirst. Who killed him?
A argues that C never drank the poison. B claims that he only deprived C of poisoned water. They're both right, but still C is dead. Who's guilty?
