There is a beauty in all of the Presidential pardons. Biden pardoning his family and Dr. Fauci means that all of these people will not be able to claim the 5th amendment right not to be forced to incriminate themselves in trial testimony. In practical terms, they will all forget everything, and non-testimony means at most a few months in jail.
While Trump pardoned 1500 Washington protestors, they have no hidden knowledge. Everyone knows that Nancy Pelosi should be the one in jail, for intentionally forbidding crowd control people until a riot was ensured to happen.
What you won't see is the CIA people explaining how they intended to release a disease upon Americans, using the Chinese as fall guys, hyping it up as a serous plague, and pushing the Democrats to use it to create a multitude of election frauds during the 2020 elections.
