Jim Jones clearly planned his mass killing for years in advance. He gathered together the people. He abused them physically, sexually and mentally. He isolated them in South America. He rehearsed a mass poisoning over and over again. On more than one occassion he served his congregation wine, and then announced it was laced with poison. Then he went on preaching while they waited to die. When they didn’t die, he told them it was a "loyalty test." Given all that, and the facts that he organized a group of armed guards to prevent the people from running helter skelter into the jungle, and that he organized (clearly in advance) the ambush of congressman Ryan and his entourage, given all this careful pre-planning, why did he post a large sign at the center of the pavilion where the murders took place, directly over his "throne" that read: "Those who cannot remember the past are condemned to repeat it?" (This quote is from the Spanish/American writer George Santayana.)
