Banned History Channel video: Government involved in John F. Kennedy assassination

This was actually a really good presentation. Is it true? Who Knows, but it sure gives a decent case study to consider.....

Uh, just who "banned" a video?

Similarly in a supermarket tabloid today it was asserted there was proof JFK was shot by second assassin,, who knows the govt sure wont tell us as they avoid all topics,,,,

JFK was shot by one man, Lee Harvey Oswald. Period.

Did anyone notice that Oswald seemed to have no memory or response to questions about the assassination? Similar to Sirhan after RFK was killed. Can you say Manchurian Candidate?
There were many involved and had prior knowledge and after.
In the 1960's, according to Hoover, there was no such thing as the" Mafia". The CIA and Mafia worked closely together during that time.

CIA
Mafia
LBJ
J.E. Hoover
H.L.Hunt
Clint Murchison
Billy Sol Estes
Malcolm Walker

Who had the biggest motive to get rid of Kennedy?
