Guy Bannister is a former FBI Agent-in-Charge from Chicago.

In 1963 Bannister ran a "Private Detective Agency" in New Orleans.

That office was located at the corner of 531 Lafayette St. & 544 Camp st.               

Both addresses shared the Same entrance.  (see below)

That office was in reality a front for a CIA backed Anti-Castro Organization.

544 Camp Street is the address that Oswald stamped on his "Fair Play For Cuba" pamphlets.

In effect, if you were inclined to be a Castro Supporter & took that literature to that address, you would have actually been Exposing yourself to an Anti-Castro organization.

That Pro-Castro literature was picked up from the printer by someone "Other than Oswald".  (see below)
