Game Theory re. Declass and Indictments
Why are Agencies not Declassifying docs?
Are they Blocking or Assisting?
Declas makes many forms of evidence public.
There is power and leverage in Prosecutors not showing all their cards too early.
A GJ is not required to be shown all evidence that a prosecutor has against a defendant.
A prosecutor will show GJ enough to gain a indictment, but not much moar.
A prosecutor may want to hold his/her best evidence close so he can gain leverage on defendant, and so others conspirators are not apprised of the totalitarity of evidence against them. In a case where there are many involved in collusion, a RICO or conspiracy we can assume when one party sees evidence the others will find out. This is particularly true where many lawfirms work together and/or have connection to DNC, Brookings, CFR, etc. (look what Flynn lawyers did to him originally)
A defendant is required to enter a plea based upon the indictment, they also may seek a deal and agree to cooperate and plead guilty to avoid trial.
All the evidence needs to be shared with defendant only during the Discovery phase of a trial. Showing all evidence will reveal all the tools utilized that may not be public until this point, and will alert others who are involved of evidence against them and may give them a heads up and a chance for DS to counter.
When a defendant wants a deal or is planning to plead not guilty, a prosecutor can get statements during interviews, etc. (think brennan) and catch a person lying. The prosecutor may then reveal a bit more evidence and ask a GJ for a superceding indictment, or ask for moar cooperation as the charges mount, or may force a defendant into pleading guilty (without having to go through discovery).
In complex cases involving many conspirators declas can affect the ability to gain cooperation, may reveal the methods available to prosecutors in gaining evidence, etc., so i am not surprised that much is being withheld from the public at this point, if any declas material is valuable, it is likely moar valuable to a prosecutor.
