"Mystery", "Apparently", "Supposedly", "Perhaps", "allegedly"
The only terms that can be applied to the secretly missing, bullet penetrated brain, of an Assassinated U.S. President under lock and key in the Fricking United States Archives of all places, under the same roof our constitution is located no less.
Spirited away in a coffee can size container that you cannot just shove in your hip pocket while nobody is looking.
Here is a fact , and not a supposed , maybe, perhaps, fact I can tell you about the National Archives, the day the Presidents brain left the National Archives , there was a person in charge who was fully accountable for it's leaving the building, and identifying who it left the building with , and for how long it was to be gone from the building. & for what purpose it was leaving the building ALL DOCUMENTED UNDER PENALTY OF FEDERAL LAW.
And knowing all these facts here is something else I know without even looking into it .
The National Archives employee that was accountable and was made fully aware the day that the President's brain left the building, was assured by the sneaking criminalistic conspiratorial thieves that the federal crime of it's undocumented theft would never be traced back to the day they were accountable for it's security and it disappeared , because nobody would ever know the day it was taken .
