Maybe explains Hillary's trip to India
Back then, we considered the possibility of indictments without their being arrested yet, but there was no way to tell.
You have to show that an organization is criminal before RICO can be used. Gambino family has been shown to be criminal, so people associated with it can be taken down by RICO. It's how they got the bosses when little other evidence existed against them. Exposing CF crimes would take down the few people who are actually part of the CF, with additional RICO charges or not, but RICO couldn't be used to prosecute someone who bribed the CF.
The content of the emails would show everything the CF did and more.
Unless Hillary won the election. Then Comey could've kept being the govt crime family capo
