I can safely say, I don’t know. There is operational secrecy
I can speculate there are special operations forces from a host of nations. I can speculate there are locals tapped for their real knowledge of purely local comings and goings. I can speculate that a cell phone is the transmission source for information passing to who knows where for storage until there is enough to conclusively promote action.
In your thoughts, who are the eyes on the ground?
I hope it is the CIA, but no matter who it is we are putting one hell of a lot of power in their hands. I wonder what kind of controls we have it is paid informants?
