A conspiracy also means cabal. A cabal of means if they can kill all these people and keep it quiet.
The kicker though is this is financial stuff, that tells me what they are covering up is serious market or banking system manipulation, looting, or some other kind of thievery.
And we’re talking about serious money, serious enough that it should scare the hell out of everybody.
They can’t kill everybody, but they can buy off the majority.
