The fake info in the fake dossier was used as the pretense for the surveillance of the Trump Campaign.
It was to cover the FBI’s ass in case it was discovered, which they knew wouldn’t happen when Hilliary was coronated.
Obama could then directly spy on the Trump campaign without fear of discovery.
This makes Watergate look like a jay-walk...................
Of course this highly partisan Deep State FBI used the fake dossier as further justification for continuing the assault on the Trump Administration, by whatever crumb of rationalization they may be able to expand upon.
Not only that, the FBI was very likely complicit in the fabrication and funding for the dossier in the first place, as a partisan action to protect and preserve the Obama-Clinton legacy.
Commit no petty crimes. That does not pay well, and the chances of detection are much higher than with huge gambits that involve the very integrity and reputation of an organization long recognized for “impartiality”.
