Oh I think the FBI has a pretty full story, but is chasing down various loose ends and people involved.
We’re the ones who don’t know what motivated this man to plan a massacre!
And they may never tell us. Be aware that the FBI Las Vegas SAC Aaron Rouse was promoted by Comey to that position in late July 2016 after having been section chief in the Counterintelligence Division.
Yes, the same Counterintelligence Division which ‘fixed’ the Hillary Espionage Act investigation into her classified emails.
Comey ‘cleared’ Hillary on July 5 and then promoted this guy to SAC status later that month. He’s a deep state apparatchik.
And I should add, also the same Counterintelligence Division which apparently used the phony Steele Dossier to get a FISA warrant to spy on presidential candidate Trump’s campaign.
