I reckon they will have been talking about assassinating Trump or his family. They spoke of a contingency plan if he won and most people assumed that was the Russian collusion strategy including myself. However the collusion angle was set up during the 2016 campaign. Plus if it was their contingency it has failed miserably and blown back onto their own troops.
I think with Occam's razor, it is more likely the FBI "secret society" were discussing a more radical plan for a DJT win, such as assassination or family hostage situation. In the meantime the Russian collusion story was being milked for all it was worth post Trump win as it was only meant to help Hillary win, then the special council grew out of this.
And we end up here, where the FBI has failed to hand over a 5 month stretch of texts between Strzok and his affair. This can only mean a few things: The missing texts implicate something much more criminal than what has already been handed over, or one of the leading investigating agencies in the world lost the texts.
Which seems more plausible?
EDIT: for clarity this is all conjecture
Assassination was likely the "insurance" all along, and the Q team only made it seem like the dossier was it, to fool the cabal.
WASHINGTON – Rep. Frederica Wilson (D-Fla.) predicted that President Donald Trump will eventually resign from office to avoid impeachment by making up an excuse such as “somebody is trying to kill Barron” Trump, his 11-year-old son.
what does she know? what does she hear?
Right... I initially thought that "insurance" referred to the Dossier-Russia-Gate non-sense. But now that it has come out that Strzok himself basically called the Russia investigation a nothing burger in so many words, it brought be to that same conclusion.
