You're absolutely right, Jerry....... The government lies , and their propaganda agency regurgitates the lie and invents convincing information to convince the suckers that the governments tale is the truth.
Last week I watched a BBC documentary about a 'third rate burglary' in other words the Watergate Affair. The British excel in these types of programs, in a way they still "rule the waves" I suppose.
It showed how a high-level conspiracy worked and was organized. In this case, the President expressed his desire to develop a political intelligence capability after leaks of classified information to the press. His wish was sent down the White House hierarchy through Haldeman and Ehrlichman, at a point people who had experience in covert operations like Hunt and Liddy got involved, who in turn hired the Cubans to execute the burglary and install the wire tapping devices.
Not sure if something like this happened in the JFK assassination, as spying on the opposing political party and enemies of the state is a whole different ballgame than the murder of a US president. And just look how quickly the Watergate cover-up collapsed.
