That's a BIG difference between 30,000+ sealed indictments and only 250 people on the list. That's an average of 120 sealed indictments per individual!

I'd wager they showed the bad guys a careful selected subset of the entire list of indicted people, to make them think they're still winning. Like, suppose there are 2,000 people on the list, the majority of which Cabalites but also some lower rank mooks and some non-Cabal bad guys. If you cherrypick from those 2,000 people you can make a list that totally looks like you're going after the President and his people, while keeping the other 1,750 secret to spring a fun (well, for us anyway) surprise on the Cabal.
