Maybe somebody told you about this case…

Notice that it refers to "an indictment" … "which was unsealed yesterday". That means that a single sealed document led to the arrest of 30 people. Now, not all indictments cover so many people, and some of the sealed documents are support documents like search warrants and witness subpoenas.
But it is likely that there is some kind of multiplier to the 28,900 CURRENTLY SEALED indictments that will predict the number of arrests. Will it be 100,000 arrests? 300,000? Or half a million? We will have to wait to find out, but looking at the details of where these sealed documents are filed (every single federal court district) suggests that the DOJ expects the system to be running at full capacity when the arrests really start rolling.
I noticed that the increase in sealed documents is slowing down. This likely means that DOJ lawyers and investigators are nearing the end of new cases, and therefore THEY WILL HAVE THE RESOURCES FREE TO RAMP UP PROSECUTIONS. None of this happens by magic. They have to build a case, get the evidence, file charges, and only then arrest people. And at that point it ain't over. They have to deal with bail requests, set trial dates, get juries in place, and then actually prosecute each case one by one. Lots of lawyers needed. And lots of judges.
They do not want this to be a FIASCO like in Tuirkey where Erdogan moved to arresting masses of people before they had the resources in place to deal with so many criminals.
Better to let the criminals think they haven't been outed yet, and watch them like hawks to find out who else is involved in their RICO criminal organization. Then take ALL OF THEM OUT.
