Actually, I was just "pinning" (I don't Pinterest but too many friends think Wikileaks is a "terrorist organization", so I joined Pinterest and started putting up pretty pictures that link to easy-to-follow articles).
Eg, earlier this year,
Scientific American published about DNA harvesting of criminals, and how little of that data was stored because of storage problems. (Heh, we know better now, thanks to Snowden).
Interesting piece, especially given that
Wikileaks exposed the U.S. (HRC in particular) secretly demanded DNA samples of all world leaders a few years ago. I hope that if one read the nice SciAm article about DNA collection of criminals, then the even
older article about Hillary wanting world leaders' DNA, someone might start to wonder why the government is collecting all this DNA ...and if it stops at "criminals" and world leaders.
So my next pretty "pin" was to
a recent article from The Atlantic with the byline: "In the not-too-distant future, they may provide something more as well—the basis for
the creation of personalized bioweapons that could take down a president and leave no trace." ZINGER!
They don't need a gas chamber or guillotine; and as for how they would procure Americans' DNA, I "pinned" how
the U.S. used a FAKE vaccination program to locate Bin Laden's family. And those doctors aren't even American; can't be threatened with an audit, or a loss of license; the US doctors
can be extorted into collecting everyone's DNA! There's
a similar article at Scientific American, only they merely "worry" about the ethics, unlike The Atlantic which seems to understand the technology is here now (though the byline says "in the not-too-distant future." They mean, "yesterday".)
And there's another "pin" I will post, about how a DNA bio-weapon could even more easily target entire races for some good old-fashioned "ethnic cleansing", no explosions necessary!
But anyway, to your point: the U.S. could probably kill anyone without a trace using a bio-weapon geared towards DNA, and harvest organs cleanly. Isn't that special!
