This post on hard Left-wing astro-blog Starlight News nails a good part of what's going on in America today. The current transiting Saturn square to the US Moon is reflective of the current rash of protests nationwide against the killing of black men Michael Brown and Eric Garner by perceived police over-reach. From what I can tell, the Eric Garner case is clearly an act of police aggression; the Brown case is murky.
As I've documented before, the Moon and the sign of Cancer seem to come up when race is a primary issue. So it's consistent with the Saturn-to-US-Moon square that the current protests are ethno-centric despite the undeniable fact that US police officers seem to feel free to kill anyone regardless on race.
But of course, the issue is not merely race but police and violence. Pallas, conjunct the US Moon, represents both ethics and armaments. Pallas conjunct the Moon in a natal chart very much represents the "warrior" aspect of Pallas made physically manifest. It's not just the US Moon that is experiencing the Saturn transit, but the US Moon-Pallas conjunction. This is why the current unease is not about race alone but about race and the ethics of violent force. To those unfamiliar with this blog, Pallas is the subject of most of the posts here -- I am not guessing or making stuff up but reporting what I've gleaned over the study of over a thousand charts on the subject of Pallas.
The US progressed Pallas is at 13 Pisces right now, receiving a sextile from Pluto. I've posted a fair amount about Pluto-to-Pallas transits. They represent an "ethical crisis" in which our sense of right and wrong and our ability to refrain from acting before due consideration are put to the test. These transits are also the "smoking gun" behind virtually all the killing/suicide events I've studied. I don't expect mainstream America to be thinking clearly over the next month or so.
