Very interesting. That Martin Luther King must be wrong, pretty sure he had a T-square. Unless I overlooked it, and if I did I really do suck.
Oddly enough, almost used Bill Gates as an example of someone with no earth, he's kind of famous for that. That's what I mean, very weird approach to solving commonsense stuff, at least the idea of computers was considered that at the time. An impractical way to solve practical matters.
Charles Manson I was being polite. I was worried he was your grandfather or something, don't like to tell people their relatives have the chart of an axe murderer. On the other hand, such a chart can also bring on revolutionary greatness--depends on the man. But generally I would give a wide berth to anyone who has a Saturn or Uranus singleton in the 12th house, especially in a fire sign, especially in Aries.
I could do that, pick out the serial killer out of five charts or something. But I could also look up that birthdate info online, wouldn't be a very rigorous test.
That's what Bob Marks is doing, coming up with an astrological protocol for general characteristics of serial killer charts. Would be unsportsmanlike to horn in on that going for the million, but I'm happy to do it here. Problem is getting accurate birth times for the killers.
Now I'm wondering if Manson was ever married. Oy, I take this stuff too seriously.
BTW, 12th house is the house of secrecy, dreams, insanity, spirituality, psychic power, hospitals, prisons, and any confinement or incarceration. So my guessing "something kept hidden" was the wrong guess. Imprisonment was the answer. Another reason why astrology is maddeningly vague.
