Me thinks a classic CIA misdirection job...50 years and counting!
According to this 50 year anniversary book (one of many), it was New Orleans Mafia boss Carlos Marcello as the highest person behind the killings (JFK and Oswald), yeah right.
With over a 1,000 books on record covering this tragedy and two official govt investigations that conflict with each other...and by the way the most current and comprehensive investigation (the U.S. House Select Committee on assassinations - USHSCA 1978-79) is most often ignored by the establishment - it concluded their WAS a CONSPIRACY and then it went no further! This book is a quick read with a great deal of Carlos Marcello history. But Vaccara must not of read or studied the wealth of other information available.
