Sure, they tried to figure out how to do “mind control”, back in the 50s and 60s. The results were pretty disappointing, if you read the declassified files. Also, there have been assassins, massacres, and “going amok” since long, long before any of those experiments, or the CIA existed, so “mind control” isn’t necessary to explain any of that.
Just because the government investigated something doesn’t mean they got it to work, and have some secret program still running. Or do you also think that, just because they investigated UFO reports, that aliens must be real and the government is covering that up?
LOL!
As if the government would release any effective results from being classified. We only get to hear about what does not work. Whether they found anything that did work could well be another story altogether.
Believe what you will.
By the time it is demonstrated on Leno, the R&D folks are well on the way to the thing after next.
