Non-Linear Technological Unveilings

Burdens of conspiracy theory epithet include MSM articles stating... uniformly, that "conspiracy theorists believe.." followed by the most preposterous version of anything from Space Lizards to the the execution of JFK.

For example:

"Conspiracy theorists believe JFK is chill-axing with Elvis in a Pakistan Madrasa"

My first experience of the Zapruder film-hoax was in B&W.

Here it is, in colour.

The Las Vegas shooting, official version states that there is no known motive, over two years later.

Fishy? 

Make your own mind up.

What's the point of speculation, when the only respected speculators on the planet are on Wall Street and/or Corporation City of London.

Has technology been seeded, or withheld from time-to-time to achieve a variety of objectives?
