In my opinion, the video is very clear. Nearby sodium lighting experienced a surge of power at nearly the same time as the Guidestones exploded into pieces, indicating a powerful electric field in the area.
There was no orange flash indicating high explosives and no saboteurs were caught on camera.
A lightning strike can be ruled out because there was none in the area at the time of the strike. Even if it was lightning, the time of the strike, 4:03.33, is a message only capable of being delivered by a DEW, which travel at 186,000 miles per second.
If it is known that this was a DEW strike, that would mean the US Military is responsible. They are the only ones with the available technology and control of Theater.
I had strong suspicions about the strike on the George Floyd mural for similar reasons.
I believe the fruits of POTUS45's formation of Space Force are now being realized.
I have designed them and analyzed target effects. This was not a laser weapon (and there are no others). Just a simple demolition charge.
Reflection off dust or vapor. Who knows? You are trying to extract too much information from a data source that is inadequate.
New data. The Georgia Bureau of Investigation has released video of a culprit approaching and then leaving the stones. Ka-boom. When data is poor, don't assume outlandish explanations (Occam's Razor).
