Sidney, et al., should have had a judge issue a Cease And Desist or Restraining Order (I don’t know the legal lingo) to these people the minute shredder trucks showed up.
The way I read the paragraph is, I think she knows Dominion is pulling up shop, and she trying to get the FBI, DOJ, ect. Involved to get over there and seize documents before they shred them. If they are pulling up shop, I’m sure document shredding was most likely the first thing they did.
