I'm saying that when it wants to, the shadow government (CIA, NSA, military, FBI, etc.) takes things into it's own hands and does what it wants. Some challenges aren't worth it to them, some are.

Kennedy was fed up with the CIA and was about to put severe limits on it. They did him in. In fact, they did both Kennedy's in. Used a classic scheme. Find a nut to do the job, then kill the nut. Tell me Jack Ruby wasn't acting under orders from someone. Sirhan was so crazy they did not have to kill him.

My point is that the "shadow" government is now so strong it is able to do pretty much what it wants to and that includes assassinations within the US and outside. They bombed an al-Jazeera news office, a Chinese embassy and a Doctors without Borders hosptal, all just to warn folks. (The "mistaken identity" card can be played only so often, and the US military has worn it out.)

My point is that there are rogue elements in the US government who do whatever they want to do without fear of accountability.
