This is a rumination on lies — layer upon layer of lies — told by US intelligence agencies and other officials about what Lee Harvey Oswald, or someone pretending to be him, was allegedly doing in Mexico City just weeks before the Kennedy assassination. The original goal, it seems, was to associate Oswald, in advance of the events of Dealey Plaza, with the USSR and Cuba.

The essay focuses on tales told by Richard Helms, a top official of the CIA in 1963 who later became its director — and  is based on a talk given by Peter Dale Scott.

Scott is the popularizer of the expression, "Deep Politics," and a virtuoso when it comes to what sometimes seems like grabbing smoke — capturing proof, however elusive, of motives and objectives that could explain  the machinations of US intelligence agencies — and then analyzing the residue.
