Newly discovered, in abirato speak, means newly created. No mention of where this new footage is “discovered”.
JFK’s assassination was the first hoax of the TV generation, and emboldened its creators to do the Apollo hoax. With that, they picked up the pace and put the hammer down in the 90s, culminating in 9/11.
This photo appears doctored. Proportion of head to body isn’t quite right.
Expect to see much, much more JFK stuff as the 50th anniversary gets big media coverage.
