Option 1 -- There is a real white hat operation going on.
If there was a real White Hat operation going on then I expect the following.
1. They have access to emails, text messages and phone calls. Even if they don't want to use them in a trial, they have known for the last 2 years who is involved in all of this.
2. They used the geotracking of the cell phones that we saw in 2,000 mules to identify the mules and to flip many of them to help with the sting operation.
3. As soon as the election was over they used the sting operation of the mules to go after higher level people in the NGO's to get them to flip.
4. The military's space force has monitored all the traffic between the Dominion machines. If they can tie this to a foreign power as we were led to believe in the movies "Absolute Proof" series then all of this other information ties into treason for everyone they have in this net of theirs.
5. I would think right now they are meeting with some of the bigger fish, going over the evidence they have against them and seeing who will cut deals.
Now if they are doing that, you can't keep it secret for long. Also you do not want anyone who was elected fraudulently to be certified. In 2020 the certification took place Dec 17.
However there are other factors at play. Will the lame duck session try to damage the US in some way? We are on the verge of war with China and Russia. Meanwhile the world's central banks appear to be dumping the US currency as the reserve currency for gold. Not only so but we seem poised for a winter where people either freeze to death or starve to death. My point is the military may not be able to wait till the optimum time since the country could collapse while we wait.
Not only so, but if the evidence points to interference from China and/or Russia then I would not expect them to sit around and wait for us to declare war on them. People are speculating that the slow walk on the election is to "demoralize" the populist movement and "rob Kari Lake of her press time". Suppose instead it was to give Russia and China time to finalize plans for a surprise attack.
Option 2 -- There is no white hat operation going on
Now the other option is that all this is a farce. Trump was bluffing when he talked about "Drain the swamp". The impeachments and Mueller investigation were all just good fun, Zuckerberg spent $400 million on the election because he passionate about the issues, and even though the Dominion machines could be used to steal an election our officials are too trustworthy and virtuous to even consider something like that. No one wants to win like that. Even if no one ever knew, they would know.
