My first thought was this is impossible,and the work of deranged paranoids with a rich fantasy life.
My second thought is of the unnecessary siege at Waco,Texas that resulted in all those people dying to keep the BATF from being disbanded,and before that the siege in Idaho where a FBI sniper was given orders to murder a innocent woman standing in her doorway holding her baby,and the siege started because some BATF turd opened fire with a machine gun on a 13 year old boy and his dog,and then the senior agent lying about it under oath,and NOTHING happened to him after it was proven in court that he had committed perjury other than he was promoted and so was the FBI sniper that murdered Vicky Weaver.
