My brother had his first job at Justice defending the government on FOIA requests - the equivalent of being a wash room attendant - millions of guys like harry asking about Kennedy, aliens, what the FBI has on them, etc. Basically his summary and the view of all the poor sots on the inside is that:
-Oswald shot Kennedy, there was another gunman on the grassy knoll who missed, and it was a mob hit ordered by Carlos Marcello. 20 people heard the shot from the Knoll and they were not kooks. Ruby was clearly tied up in the Mob, and Oswald had plenty of contacts with the mob too.
-Nobody can explain Oswald's Mexico City trip.
-The FBI people stick to the Warren Commmission findings.
-They do not believe the LBJ theory, the soviet theory, the cuban theory, or the lone gunman/Warren Commission theory.
I go along with his line I guess but if Marcello did it, I wonder if he worried that if they blew it or somebody talked - that there could have been wholesale reprisals against Italian Americans in this country for no other reason than their ethnicity.
I'm sure Teddy has gotten right with what really happened down there too but he's always kept still to my knowledge.
