Final Judgment · The Missing Link in the JFK Assassination Conspiracy

Piper claims John F. Kennedy's assassination "was a joint enterprise conducted on the highest levels of the CIA, in collaboration with organized crime ...the Israeli intelligence service Mossad." In his underground best-seller, Final Judgment, he posits that Israeli prime-minister David Ben Gurion was the prime mover in his assassination. It was due to disputes with Palestine Egypt, plus Kennedy's attempts to halt Israeli atomic research. This theory also seeks to tie in other Kennedy assassination theories, primarily involving Jewish mobster Meyer Lansky's organizing the hit, future president Lyndon B. Johnson staging the event from inside the administration. He also alleged that the Anti-Defamation League also was linked to the murder. The ADL responded with harsh criticisms, called the claims ridiculous denounced Final Judgment as anti-Semitic.

Additionally, Piper has written articles in American Free Press claiming that Mossad the FBI conspired to set up the assassination of Martin Luther King, Jr. This was motivated by fear of King's anti-Israel statements combined with his massive grassroots power.
