Sadly the heads connected to the bodies they reside on fail all the time.
Until the majority of the secrecy in the 'intelligence' agencies is removed, our republic will never be free. We got here because the military got used to secrecy in WWII never had to answer for their own atrocities during that war. We will always be ruled unjustly as long as that system is in place. I, like everyone here, have no idea if Trump will/can/wants to dismantle that system, but if he does not, the country will be here again in short order. An elite that can hide behind 'state secretes' will always fall into the trap of power.
