Mixing truth and untruth to confuse and discredit has been a time honored method used by TPB for a very long time. JFK/Warren Commission a good example.
Pizzagate incident was perhaps beyond discrediting - it seemed like a cleanup operations possibly. Declaring it a crime scene after a “lone nut” with a gun— allowed officials to keep out prying eyes, collect, conceal, and dispose of any evidence that the guilty wanted to get rid of.
Two birds with one bullet.
Very good description.
